Field Summary
`static short` | `VALIDATION_FULL` Validation status indicating that full schema validation has been performed on the element.
`static short` | `VALIDATION_NONE` Validation status indicating that schema validation has been performed and the element in question has specifically been skipped.
`static short` | `VALIDATION_PARTIAL` Validation status indicating that schema validation has been performed on the element in question under the rules of lax validation.
`static short` | `VALIDITY_INVALID` Validity value indicating that validation has been strictly assessed and the element in question is invalid according to the rules of schema validation.
`static short` | `VALIDITY_NOTKNOWN` Validity value indicating that validation has either not been performed or that a strict assessment of validity could not be performed
`static short` | `VALIDITY_VALID` Validity value indicating that validation has been strictly assessed and the element in question is valid according to the rules of schema validation.

Method Summary
`org.apache.xerces.impl.xs.psvi.StringList` | `getErrorCodes()` A list of error codes generated from validation attempts.
`boolean` | `getIsSchemaSpecified()` [schema specified]
`org.apache.xerces.impl.xs.psvi.XSSimpleTypeDefinition` | `getMemberTypeDefinition()` If and only if that type definition is a simple type definition with {variety} union, or a complex type definition whose {content type} is a simple thype definition with {variety} union, then an item isomorphic to that member of the union's {member type definitions} which actually validated the element item's normalized value.
`java.lang.String` | `getSchemaDefault()` [schema default]
`java.lang.String` | `getSchemaNormalizedValue()` [schema normalized value]
`org.apache.xerces.impl.xs.psvi.XSTypeDefinition` | `getTypeDefinition()` An item isomorphic to the type definition used to validate this element.
`short` | `getValidationAttempted()` Determines the extent to which the document has been validated
`java.lang.String` | `getValidationContext()` [validation context] // REVISIT: what the return type should be? Should we return QName/XPath/ or element info item..?
`short` | `getValidity()` Determine the validity of the node with respect to the validation being attempted

  Validity value indicating that validation has been strictly assessed and the element in question is invalid according to the rules of schema validation.

### VALIDITY_VALID

    public static final short VALIDITY_VALID

  Validity value indicating that validation has been strictly assessed and the element in question is valid according to the rules of schema validation.

### VALIDATION_NONE

    public static final short VALIDATION_NONE

Method Detail

### getValidationContext

    public java.lang.String getValidationContext()

  [validation context] // REVISIT: what the return type should be? Should we return QName/XPath/ or element info item..?
  Returns:
    The nearest ancestor element information item with a [schema information] property (or this element item itself if it has such a property)
  See Also:
    XML Schema Part 1: Structures [validation context]

### getValidity

    public short getValidity()

  Determine the validity of the node with respect to the validation being attempted
  Returns:
    return the [validity] property. Possible values are: VALIDITY_UNKNOWN, VALIDITY_INVALID, VALIDITY_VALID

### getValidationAttempted

    public short getValidationAttempted()

  Determines the extent to which the document has been validated
  Returns:
    return the [validation attempted] property. The possible values are VALIDATION_NONE, VALIDATION_PARTIAL and VALIDATION_FULL

### getErrorCodes

    public org.apache.xerces.impl.xs.psvi.StringList getErrorCodes()

  A list of error codes generated from validation attempts. Need to find all the possible subclause reports that need reporting
  Returns:
    list of error codes

### getSchemaNormalizedValue

    public java.lang.String getSchemaNormalizedValue()

  [schema normalized value]
  Returns:
    the normalized value of this item after validation
  See Also:
    XML Schema Part 1: Structures [schema normalized value]

### getTypeDefinition

    public org.apache.xerces.impl.xs.psvi.XSTypeDefinition getTypeDefinition()

  An item isomorphic to the type definition used to validate this element.
  Returns:
    a type declaration

### getMemberTypeDefinition

    public org.apache.xerces.impl.xs.psvi.XSSimpleTypeDefinition getMemberTypeDefinition()

  If and only if that type definition is a simple type definition with {variety} union, or a complex type definition whose {content type} is a simple thype definition with {variety} union, then an item isomorphic to that member of the union's {member type definitions} which actually validated the element item's normalized value.
  Returns:
    a simple type declaration

### getSchemaDefault

    public java.lang.String getSchemaDefault()

  [schema default]
  Returns:
    The canonical lexical representation of the declaration's {value constraint} value.
  See Also:
    XML Schema Part 1: Structures [schema default]

### getIsSchemaSpecified

    public boolean getIsSchemaSpecified()

  [schema specified]
  Returns:
    true - value was specified in schema, false - value comes from the infoset
  See Also:
    XML Schema Part 1: Structures [schema specified]
