| Xerces-J 2.9.1 |
| This release fixes several bugs which were present in Xerces-J 2.9.0. It also includes a few minor enhancements and performance improvements. Added support for creating UIEvents and MouseEvents through the DOM Level 2 Events API. `[Michael Glavassevich]` Improved the reporting of character conversion errors. The CharConversionException which triggered the fatal error is now available from SAXException.getException(). `[Michael Glavassevich]` Reduced the performance penalty for using an EOFException internally to signal to the scanner that the end of the document has been reached. The exception is now cached, avoiding the expensive fillInStackTrace() on creation. `[Michael Glavassevich]` Improved the performance of the XMLGregorianCalendar implementation. `[Michael Glavassevich]` Implemented improvements in the processing of large minOccurs/maxOccurs on element/wildcard particles which once caused OutOfMemoryErrors to occur during validation. Note that an OutOfMemoryError may still occur if the minOccurs/maxOccurs are nested or appear on a sequence or choice model group. `[Michael Glavassevich]` Improved the algorithm for checking the Unique Particle Attribution constraint so that it no longer causes an OutOfMemoryError for content models with large maxOccurs values. Note that this only applies to the checking of schema validity. An OutOfMemoryError may still occur if the schema contains large maxOccurs and is used to validate an instance document. `[Peter McCracken]` Completed the implementation of XML Schema erratum E2-67. `[Ed Merks, Khaled Noaman]` Implemented XML 1.0 Third Edition erratum E13. `[Michael Glavassevich]` Fixed bugs in the implementation of Document.normalizeDocument() where it was not correctly re-evaluating Element.schemaTypeInfo, Attr.schemaTypeInfo, IDness or the [element content whitespace] property of text nodes when validating against a DTD or XML Schema. `[Michael Glavassevich]` Fixed a thread-safety bug which could cause an ArrayIndexOutOfBoundsException or a NullPointerException to be thrown during DTD validation if a grammar pool is shared between multiple parser instances. `[Michael Glavassevich]` Fixed a bug in the DOMConfiguration of a Document where it was processing the "schema-location" parameter as an atomic URI value instead of a whitespace separated list of URIs. `[Michael Glavassevich]` Fixed a bug in the XInclude implementation where the Locator would report the location of the xi:include element in the top-level document as the location of all the document events in the included document or fragment. `[Michael Glavassevich]` Fixed a bug in the JAXP schema validator which caused it to fail with a third-party DOM Level 3 implementation whose nodes can only be tested for identity using isSameNode(). `[Michael Glavassevich]` Fixed several bugs in the XML schema processor which were exposed by running the W3C's XML Schema 1.0 2nd Edition test suite. `[Michael Glavassevich]` Fixed several bugs in the DOM Level 2 Traversal and Range implementation. `[Michael Glavassevich]` Fixed various bugs and made various improvements. `[Dave Brosius, Michael Glavassevich, Khaled Noaman]`
| Xerces-J 2.9.0 |
| As of this release, Xerces and Xalan now share a common serialization codebase. The DOM Level 3 serialization support which was in Xerces was migrated into the Xalan serializer and Xerces' native serializer was deprecated. In this release we also upgraded the xml-commons resolver to v1.2 (which provides support for OASIS XML Catalogs v1.1), introduced a few minor features and fixed several bugs. Migrated the DOM Level 3 serialization support onto a common serialization codebase shared with Xalan and deprecated Xerces' native serializer. `[Neil Delima, Michael Glavassevich]` Upgraded the xml-commons resolver to v1.2. This new version of the resolver adds support for OASIS XML Catalogs v1.1. `[Michael Glavassevich]` Created a new parser configuration which uses a memory sensitive SymbolTable which can handle usage scenarios where the names in the XML documents being parsed are mostly unique. The internalized strings stored in this SymbolTable are softly reachable and may be cleared by the garbage collector in response to memory demand. `[Peter McCracken]` Updated the schema loader so that it can now process schema documents with an XML 1.1 declaration. `[Michael Glavassevich]` Fixed several bugs in the checking of schema type restrictions that involve substitution groups. `[Lucian Holland, Ignacio Hernandez-Ros]` Fixed a bug in Xerces' regular expression support where patterns containing "$" and "^" were being interpreted as anchors in a schema context. `[Chris Carman]` Fixed a bug in the XPath matcher for identity constraints which allowed steps containing NCName:* to select element or attribute names which do not match the specified namespace. `[Michael Glavassevich]` Fixed a bug in the XPath parser for identity constraints which caused field and selector XPaths containing the non-abbreviated form of the child and attribute axes to be reported as invalid. `[Michael Glavassevich]` Fixed a bug which allowed the JAXP SchemaFactory to mutate a user supplied DOM input. `[Michael Glavassevich]` Fixed a bug which caused the JAXP 1.2 method for schema validation to produce DTD validation errors when XInclude processing is enabled. `[Michael Glavassevich]` Fixed various bugs and made various improvements. `[Nathan Beyer, George Cristian Bina, Michael Glavassevich, Jacob Kjome, Grant McDonald]`
| Xerces-J 2.8.1 |
| This release fixes several bugs which were present in Xerces-J 2.8.0. It also includes a few minor enhancements and performance improvements. Implemented native support for the ISO-8859-1 encoding. `[Michael Glavassevich]` Added a method to XSModel which returns a list containing the members of the substitution group for a given element declaration. `[Michael Glavassevich]` Improved the performance of Xerces' optimized readers (for small documents) by recycling their byte buffers. `[Michael Glavassevich]` Modified the DocumentBuilder and LSParser implementations so that they drop their internal references to the DOM they just built. If an application is pooling parsers this will allow the garbage collector to reclaim the Document and all of its nodes if the application no longer has any references to it. `[Michael Glavassevich]` Fixed numerous schema annotation related bugs including those introduced in Xerces-J 2.8.0 which caused NPEs to be thrown from several of the getAnnotation() methods in the XML Schema API. `[Neil Delima, Michael Glavassevich]` Fixed a DOM bug which caused the internal subset of a DocumentType node to be omitted from a cloned Document. `[Jacob Kjome]` Fixed a bug in Xerces' regular expression support involving patterns starting with '.'. `[Kent Tamura]` Fixed a bug which caused the DOM builder to drop all of the text in the document if grammar caching is enabled and the document being processed contains both an internal and an external DTD subset. `[Michael Glavassevich]` Fixed a schema bug which allowed defaulted attributes with the same local name to overwrite each other. `[Michael Glavassevich]` Fixed a bug which caused a schema document to be loaded multiple times if it was both included and redefined. This made it possible for the redefined components to be incorrectly overwritten by the original ones from the include. `[Michael Glavassevich]` Fixed a bug in Xerces' native serializer which caused documents containing supplemental characters in attribute values to be written incorrectly. `[Michael Glavassevich]` Fixed a bug in the XInclude processor which in some instances caused content to be omitted from the result if an element() XPointer is specified on an include element. `[Neil Delima]` Fixed various bugs and made various improvements. `[Dave Brosius, Michael Glavassevich, Jacob Kjome, Peter McCracken]`
| Xerces-J 2.8.0 |
| This release introduces several new validation related features and provides enhancements to the XML schema annotation support. All of the schema component interfaces in the XML Schema API now have a getAnnotations() method which returns a list of XSAnnotations. This includes annotations on particles and attribute uses which were previously "lost". In addition, in this release we implemented support for pretty-printing in the LSSerializer, repaired the warn-on-undeclared-elemdef feature which had been broken for several releases and fixed many other bugs. Added a getAnnotations() method to each of the component interfaces in the XML Schema API (including XSParticle and XSAttributeUse) and implemented the support for the new methods. `[Neil Delima]` Implemented a property for starting schema assessment from a specific type definition. `[Peter McCracken]` Implemented features for disabling ID/IDREF, unparsed entity and identity constraint checking. `[Peter McCracken]` Implemented a feature which instructs the schema validator to ignore xsi:type attributes until a global element declaration has been found. `[Peter McCracken]` Modified the JAXP Validation API implementation so that it propagates features set on the SchemaFactory to the Schemas created from the factory and in turn ValidatorHandlers and Validators constructed from those Schema objects (as clarified by JAXP 1.4). `[Peter McCracken]` Implemented the DOM Level 3 Load and Save format-pretty-print parameter. `[Matej Kraus]` Fixed the warn-on-undeclared-elemdef feature which had been broken for many releases. `[Michael Glavassevich]` Implemented a feature which allows the parser to process DTDs containing large content models which under normal operation may cause a StackOverflowError to occur. `[Michael Glavassevich]` Improved the performance and memory usage of XSAnnotation.writeAnnotation(). `[Michael Glavassevich]` Implemented XML Schema erratum E2-66. `[Sandy Gao]` Fixed bugs in the implementation of Document.normalizeDocument() which caused DTD validation to fail in numerous scenarios. `[Michael Glavassevich]` Fixed a bug where schema validation performed in Document.normalizeDocument() was adding default attributes without setting their owner element or firing mutation events. `[Michael Glavassevich]` Fixed a bug which caused the JAXP 1.2 method for schema validation to fail when the parser is reused. `[Michael Glavassevich]` Fixed a bug which caused a ClassCastException to be thrown when adopting a node from a deferred DOM into a non-deferred DOM. `[Michael Glavassevich]` Fixed the dtdjars build target which had been broken for several releases. `[Michael Glavassevich]` Improved identity constraint error messages. `[George Cristian Bina]` Fixed various bugs and made various improvements. `[Nathan Beyer, Dave Brosius, Sandy Gao, Michael Glavassevich, Matej Kraus, Peter McCracken]`
| Xerces-J 2.7.1 |
| This release fixes one XInclude bug and several schema related bugs which were present in Xerces-J 2.7.0. Fixed an inconsistency in the validation behaviour of the parser when XInclude processing is enabled and the validation and schema validation features are also enabled. `[Michael Glavassevich]` Fixed a bug where in a DOM Level 3 context with schema validation enabled, not all schema constraints (such as unique particle attribution) were being checked. `[Michael Glavassevich]` Fixed bugs which allowed various invalid lexical values to be accepted by the schema validator for the following types: double, date, float, gDay, gMonthDay, gMonth and gYearMonth. `[Michael Glavassevich]` Fixed a schema bug where errors would be reported for comments and processing instructions which appear as the children of an element declared to have empty content. `[Michael Glavassevich]` Fixed a bug which caused an NPE to be thrown for a namespace declaration such as xmlns="" which appeared on an ancestor element of an <annotation>. `[Michael Glavassevich]`

In addition, in this release we improved parser performance in several areas and fixed many bugs. Improved the scanning of attribute lists, both small and large. `[Michael Glavassevich]` Reimplemented XML11Configuration (the default configuration), improving performance during reset; accomplished primarily by adding an internal feature which allows components to query whether or not they need to read features and properties from the configuration. `[Elena Litani]` Modified XML Schema interfaces (`org.apache.xerces.xs`) and updated the implementation accordingly. Methods were added to expose actual values and their types and new interfaces were added for loading XSModels.

This still excludes section 2.13. `[Michael Glavassevich]` Fixed a bug which could cause the parser to run out of memory (or other resources) while parsing documents containing many entity references. `[Michael Glavassevich]` Implemented missing support for Registry-based Naming Authority in the URI implementation. `[Michael Glavassevich]` Modified the XJavac task used by the build file so that Xerces can be built on Linux with Blackdown JDK 1.4. `[Amit Kapoor]` Removed static references to sun.io.CharToByteConverter which made it impossible to compile Xerces on platforms that do not have this internal class. With binaries on such platforms, the serializer was unusable with many encodings. `[Michael Glavassevich]` Added support for XML Base to the XInclude implementation. Fixed various bugs regarding text inclusion and relative URI resolution in the XInclude implementation. `[Michael Glavassevich, Peter McCracken, Neil Pitman]` Implemented errata from the XML 1.0 Second Edition Specification. `[Neil Delima, Michael Glavassevich, Glenn Marcy, Peter McCracken]` Moved Xerces' SAX support up to SAX 2.0.1. `[Elena Litani]` Fixed bugs in the XML 1.1 entity scanner that in some cases treated NEL (0x85) and LSEP (0x2028) as white space characters in internal entities, and not as end of line characters in external entities. `[Michael Glavassevich]` Fixed bug in HTML DOM implementation that would cause a hierarchy request error by trying to move a doctype node to be a child of the <html> element. `[Andy Clark]` Fixed various bugs. `[Neil Delima, Sandy Gao, Neil Graham, Michael Glavassevich, Elena Litani, Lisa Martin, Peter McCracken, Gareth Reakes, Neeraj Bajaj, K.Venugopal, Ramesh Mandava, Kohsuke Kawaguchi, Gopal Sharma]`
| Xerces-J 2.5.0 |
| This release provides a partial implementation of W3C XInclude specification as well as adds annotation support for the XML Schema component API. In addition to fixing many bugs, this release also brings Xerces into compliance with the most recent work of the W3C DOM working group on DOM level 3 Core and Load/Save, and includes additional fixes related to the XML 1.1 specification. Fixed an ArrayIndexOutOfBoundsException in the scanner caused by some invalid character references. `[Michael Glavassevich]` Fixed various bugs related to XML 1.1. `[Neil Graham, Neil Delima, Michael Glavassevich]` Fixed various bugs in the URI implementation, and added previously missing support for IPv6 addresses. `[Michael Glavassevich]` Fixed performance issue for attributes with large value field. `[Thomas DeWeese]` Implemented the latest DOM Level 3 Core and Load and Save drafts in Last Call. `[Elena Litani, Gopal Sharma, Arun Yadav, Neeraj Bajaj]` Added annotation support to the XML Schema component model API implementation.

Venugopal]`
| Xerces-J 2.4.0 |
| This release incorporates two minor changes to the Xerces Native Interface. In addition to fixing many bugs, this release also brings Xerces into compliance with the most recent work of the W3C DOM working group on DOM level 3 Core and Load/Save, and includes additional fixes based on the XML Schema errata. Also in this release, XML 1.1. is supported by default. Modified XNI XMLResourceIdentifier to include set/getNamespace. Added getEncoding method to the XNI XMLLocator interface. `[Sandy Gao, Neil Graham]` Fixed scanner implementation to be able to handle large CDATA sections without buffering. `[Andy Clark]` Made internal class loading strategy a bit more friendly in environments which need to provide classloaders to do things like manage multiple versions of Xerces. `[Igor Malinin, Neil Graham]` Improved robustness of build shell script under the Cygwin environment. `[J. Pietschmann, Neil Graham]` Fixed null pointer exception in DTDConfiguration caused when no DTD handlers are registered. `[Andy Clark]` Fixed various bugs related to <redefine> in XML Schema traversal. `[Khaled Noaman, Sandy Gao]` Fixed various bugs related to the pattern facet (regular expression) in XML Schema. `[Khaled Noaman, Sandy Gao]` Implemented the latest DOM Level 3 Core and Load and Save drafts. `[Elena Litani]` Improved performance of XML11Configuration and made it the default configuration. `[Elena Litani]` Added support for ordering disconnected nodes (DOM Level 3 compareDocumentPosition) `[Lisa Martin]` In anticipation of the DOM Level 3 Events specification, fix Xerces Events implementation to call event listeners in the order in which they were registered `[Arnaud Le Hors]` Implemented XML Schema errata as they were published. `[Sandy Gao]` Fixed a bug related the external-schemaLocation property. `[Sandy Gao]` Fixed various bugs. `[Ville Skyttä, Michael Glavassevich, Elena Litani, Sandy Gao, Neil Graham]`
| Xerces-J 2.3.0 |
| With this release, the Xerces-J developers are declaring the Xerces Native Interface (XNI) core and parsers packages to be gold. This release also brings Xerces into compliance with the most recent work of the W3C DOM working group on DOM level 3 Core and Load/Save, and introduces many fixes to bring Xerces's behaviour into line with XML Schema errata. Support for the parsing of documents written according to the XML 1.1 candidate recommendation has also been completed, except that no option for verifying that documents are normalized has yet been implemented. Finally, Xerces now provides means by which applications can force the parser to reject certain kinds of documents the processing of which could result in a denial-of-service attack. Modified XMLLocator interface to remove setter methods for move towards finalizing XNI; this change also implied removing XMLLocator's dependence upon XMLResourceIdentifier. `[Andy Clark]` Implemented several DOM Level 3 features, including DOMConfiguration, exposing type information via DOM, and allowing to set an ID attribute in the DOM. `[Elena Litani]` Modified support for DOM L3 compareDocumentPosition (formerly compareTreePosition). `[Lisa Martin]` Modified several XNI interfaces, i.e. NamespaceContext, XMLResourceIdentifier, Augmentation, XMLAttributes, and updated implementation accordingly. `[Elena Litani, Sandy Gao]` Modified PSVI interfaces (`org.apache.xerces.impl.xs.psvi`) and updated implementation accordingly. `[Elena Litani]` Modified XMLDTDHandler, XMLDTDSource, XMLDTDContentModelHandler and XMLDTDContentModelSource to make these pipelines doubly-linked, as was done in the last release for the main document pipeline. `[Neil Graham]` Completed experimental support for XML 1.1 and XML Namespaces 1.1 CR's, except for XML 1.1 section 2.13. `[Neil Graham]` Provided a mechanism by which applications can instruct the parser to abort the parsing of documents containing constructs that could swamp system resources. `[Neil Graham, Neeraj Bajaj]` Added a feature "disallow-doctype-decl" so that a fatal error is reported if this feature is on and the incoming document has a DOCTYPE. `[Sandy Gao]` Added a feature "standard-uri-conformant" so that the parser enforces the URI rules when this feature is on. `[Sandy Gao]` Performance update: ported the partial DTM implementation of DOM and use it for parsing Schema documents. `[Sandy Gao]` Provided full support for canonical representation of XML Schema datatypes. `[Sandy Gao]` Implemented XML Schema errata as they were published. `[Sandy Gao]` Fix comment parsing bug that prevented Tomcat 4.1.12 from making use of Xerces versions later than 2.1.0. `[Tim Bruce, Neil Graham]`
| Xerces-J 2.2.1 |
| This release fixes four important bugs and several minor problems that were present in Xerces-J 2.2.0. Fixed SAX endElement call so that the element's namespace URI is returned. `[Elena Litani]` Fixed HTML DOM implementation so that it can be instantiated. `[Neil Graham]` Made the external-schema-location property work again. `[Sandy Gao]` Enabled Xerces to validate the schema for schemas. `[Sandy Gao]`
| Xerces-J 2.2.0 |
| As well as incorporating two changes to the Xerces Native Interface, this release focuses on performance improvements and bug fixes. Modified XMLComponent interface so that components used in a parser configuration can specify preferred default values for settings. Also updated all classes that implement the XMLComponent interface. `[Andy Clark]` Modified XNI XMLDocumentHandler interface so that NamespaceContext objects are passed on the startDocument call. This makes the start/endPrefixMapping calls redundant; they have been deprecated. `[Elena Litani, Arnaud Le Hors]` Fixed many conformance bugs and enhanced the parser's performance in many situations. `[Elena Litani, Sandy Gao, Neil Graham]`
| Xerces-J 2.1.0 |
| As well as some relatively minor changes to XNI, this release includes many bugfixes and performance improvements. Added xni.XMLDocumentHandler.setDocumentSource/getDocumentSource and XMLDocumentSource.getDocumentHandler methods to allow to modify Xerces pipeline dynamically. `[Elena Litani]` Store PSVI in DOM tree: when the new DOM document is used, element/attribute nodes can be casted to Element/AttributePSVI interfaces to retrieve PSVI properties. `[Sandy Gao]` Provide access to PSVI via SAX using org.apache.xerces.impl.xs.psvi.PSVIProvider interface. `[Elena Litani]` Provided a way to convert preparsed schema grammars to XSModels. `[Sandy Gao]` Message localization changes. `[Sandy Gao, Neil Graham, Elena Litani, Lisa Martin]` Send all element PSVI properties on endElement calls, so that the application doesn't need to stack them when startElement is called. `[Sandy Gao]` Made it possible to build a Schema Datatype jar file. Now it can be used as a standalone data type library. `[Sandy Gao]` Performance update: avoid using exceptions to determine whether an array needs to be resized. `[Henry Zongaro, Sandy Gao]` Performance update: avoid adding the commonly used XML symbols to the symbol table again and again. `[Sandy Gao]` Performance update: improve scanning speed by skipping end tag names and using proper input buffer size. `[Neeraj Bajaj, Sandy Gao]` Applied fixes to Xerces's regular expression support to address a number of bugs reported by users. `[Kent Tamura, Neil Graham]` Provide implementation for DOM Level 3 DOMBuilderFilter and DOMWriterFilter. `[Elena Litani]` Applied fixes to JAXP, SAX and internal object factory code so that it behaves correctly in environments where AccessControllers are being used. These fixes make it no longer possible to compile Xerces under JDK 1.1.8. `[Edwin Goei, Neil Graham]` Reorganize the code again to allow to build Xerces with DOM Level 3 support and modifying the build.xml to replace import statements in the source code. `[Elena Litani]` Changed various parts of Xerces's implementation so that it is now statically immutable. `[Neil Graham]` Reorganized identity constraint support to improve both conformance and performance. `[Neil Graham]` General bug fixes. `[Elena Litani, Neil Graham, Lisa Martin, Sandy Gao]`
| Xerces-J 2.0.2 |
| In this release, numerous bugs have been fixed. Only one minor change in the Xerces Native Interface is included (documented below); considerable new functionality has also been added in terms of PSVI support, DOM level 3, and grammar preparsing/caching. Schema Component API interfaces and implementation; full PSVI support. `[Sandy Gao, Elena Litani]` Add XMLResourceIdentifier to startExternalSubset() method defined in XNI XMLDTDHandler. That allows supporting baseURI for an external subset. `[Elena Litani]` Add implementation for baseURI, documentURI, normalizeDocument and required normalize document features. Added support for DOM revalidation against XML Schemas. [DOM Level 3] `[Elena Litani]` Added implementation for compareTreePosition method of DOM L3. `[Lisa Martin]` Added XMLGrammarLoader interface to the xni.grammars package; refactor DTD and Schema validation code to create classes implementing this interface; created a convenience class (XMLGrammarPreparser) that uses the new grammar loaders to permit grammar preparsing; wrote a sample (xni.XMLGrammarBuilder) that demonstrates how all this works. `[Neil Graham]` Reorganized the code in Xerces DOM implementation to expose DOM Level 3 functionality via org.w3c.dom package. Added several build targets for building customized xerces jar files that include DOM Level 3 Core and Load/Save interfaces and implementation of those interfaces: jars-dom3, apijar-dom3, sampjar-dom3. `[Arnaud Le Hors, Elena Litani]` Updated xni.DocumentTracer sample to print augmentations for events. This makes it easier to debug configurations that augment the document's infoset. `[Andy Clark]` Removed dependence on SAX attribute interfaces from XMLAttributesImpl utility class. The AbstractSAXParser already defines a SAX attribute proxy class so that the parser and components can be properly layered. `[Andy Clark]` Moved from the org.xml.sax.helpers.AttributesImpl shipped with SAX 2.0 to that shipping in 2.0.1. This solves problems encountered with creating empty attribute lists. `[Neil Graham]` Improved handling of settings in parser classes making it easier to re-use the parsers with other parser configurations. Previously, the parser instances assumed that all configurations supported various settings (i.e. the parser would set default values without first adding the recognized features and property identifiers to the parser configuration). `[Andy Clark]` Fixed bug in HTML DOM implementation that was causing xerces.dom element nodes to be created instead of the appropriate HTML element nodes. `[Andy Clark]` Fixed bug to avoid null pointer exception in AbstractDOMParser when locator information is not available from parser configuration. `[Andy Clark]` Fixed bug in WrappedInput/OutputStream classes reported by Morten Bjørhus. `[Andy Clark]` The DTD validator failed to report "undeclared element" error if an attribute was declared for an undeclared element.`[Elena Litani]` Performance fixes: replaced code that increases array sizes by catching ArrayIndexOutOfBoundsExceptions with code that checks the sizes of the relevant arrays. Also streamlined several method calls in the DTD Grammar classes to account for the fact that scope is not relevant for this type of grammar. Finally, improved algorithm for recognizing entities and notations. `[Henry Zongaro, Neil Graham]` Compress jars by default. We have not done so in the past, and it will be useful to see if this proves problematic or beneficial. `[Neil Graham]` Added several build targets for building customized xercesImpl jar files. Now we can build a DTD-only version, and a DTD-only version also excluding support for the HTML/WML DOM. `[Neil Graham]` Parser now reads external entities one chunk at a time, rather than a character at a time; this increases performance dramatically in certain circumstances. This fix also allows a number of EBCDIC encodings to work which did not work previously. `[Neil Graham, Henry Zongaro]` Performance enhancement: implemented DOM node and declaration pools that reduce number of objects created during building of XML Schema grammars. `[Elena Litani]` Improved performance for non-deferred DOM: reduced number of concatenations for characters (bug #5602) `[Elena Litani]` According to the namespace spec errata, namespace declaration attributes should be bound to a special namespace; and errors should be reported on illegal bindings of "xmlns" and "xml" prefixes and their namespaces. `[Sandy Gao]` Refined schema error messages: provide more descriptive error messages for simple type validation errors; avoid cascading errors when a grammar for a given namespace is not found, or when components from a certain namespace can't be accessed from a given schema document. `[Sandy Gao]` Changed the lexical representation of gMonth from "--MM--" to "--MM". `[Sandy Gao]` Decimal point shouldn't be allowed in integer-derived types; "fractionDigits" and "totalDigits" should be calculated on the value space. `[Sandy Gao]` Fixed several DOM bugs. Xerces now passes W3C DOM Level 1 Core test suite. `[Elena Litani]` Improved management of ID attributes in the DOM so that Document.getElementByID is more reliable. `[Arnaud Le Hors]` Applied patch from Scott Sanders to fix Java serialization of the DOM and add a test. `[Arnaud Le Hors]` Applied patch from Henry Zongaro to fix a ClassCastException in the deferred DOM.`[Elena Litani]` Applied patch from Fabio Riccardi to reset normalize value in the PSVI. `[Elena Litani]` Applied patch from Joe Kesselman that fixes NPE in a NodeIterator (bug #6888). `[Elena Litani]`

| Xerces-J 2.0.0 (beta3) |
| This release fixes a number of bugs, introduces some changes to the Xerces Native Interface, and is the first Xerces2 release to include XML Schema validation support. Please note that the XML Schema validation code was completely rewritten for Xerces2 and should be considered alpha at this time. Redesigned and rewrote XML Schema validation code. Also updated standard parser configuration to include the XML Schema validator in the document pipeline by default. `[Sandy Gao, Lisa Martin, Neil Graham, Elena Litani, Rahul Srivastava, Gopal Sharma, Pavani Mukthipudi, Neeraj Bajaj]` Added new default parser configuration that includes DTD and XML Schema validators (DTDXSParserConfiguration).

(Bug #3449) `[Pavani Mukthipudi]` Fixed bug in SAX parser that was not forwarding external entity declarations in the DTD. (Bug #3392) `[Neeraj Bajaj]` Separated the XMLDocumentScannerImpl class so that it derives from XMLDocumentFragmentScannerImpl which enables an application to parse document fragments. `[Andy Clark]` Ported the deferred DOM implementation from the Xerces 1.x codebase. `[Arnaud Le Hors]`
| Xerces-J 2.0.0 (beta2) |
| This is primarily a bug fix release. However, a new XNI interface and additional documentation have been added. Fixed bug for when namespace bindings were added as default attributes from the DTD. `[Andy Clark]` Fixed Xerces2 standard components to properly recognize and use the features and properties that they are documented to accept. `[Andy Clark]` Added documentation to the XNI Manual for re-using the Xerces2 parser components. `[Andy Clark]` Moved Xerces 1.x to "xerces_j_1" branch and moved Xerces2 to the main trunk of the "xml-xerces" module. `[Arnaud Le Hors]` Improved ability of document and DTD scanners to perform pull parsing. `[Andy Clark]` Fixed bug where namespace binder would turn an emptyElement callback into startElement and endElement callbacks. `[Andy Clark]` Updated standard parser configuration to separate DTD validation and namespace binding in the parsing pipeline. `[Andy Clark]` Removed old XML Schema code that was not being used. This code is intended to be replaced by either a port of the Xerces 1.x XML Schema implementation or by a re-designed, re-implemented XML Schema implementation. `[Andy Clark]` Fixed bug in scanner that allowed the built-in entity references to be sent via XNI. The default value for this feature should have been false. `[Andy Clark]` Fixed several SAX bugs.`[Andy Clark]` Synchronized DOM implementation code from Xerces 1.x codebase. `[Andy Clark]`
| Xerces-J 2.0.0 (beta) |
| First beta release of the Xerces2 code. Besides numerous bug fixes, this release has changes and additions to XNI. The new XNI parser configuration framework has been added in this release. Refer to the XNI Manual for complete information. Added document and DTD scanner interfaces to XNI to allow parser configuration pipelines to be constructed generically. `[Andy Clark]` Fixed bug in DTD grammar for mixed content models that was building the wrong validation content model. `[Sandy Gao]` Removed SAX dependency from XNI framework. Now the only dependence on external API such as SAX is in the implementation of the AbstractSAXParser and DOMParser so that legacy code doesn't break. `[Andy Clark]` Rewrote existing documentation, added XNI information, cleaned up stylesheets, and converted some docs to use custom DTDs. `[Andy Clark]` DTD method ordering problem for INCLUDE/IGNORE sections.`[Petr Kuzel]` Improved DFA build-time performance.`[ATOZAWA@jp.ibm.com]` Synchronized with Xerces 1.3.0`[Arnaud Le Hors]`
