  - constant
```
ItemPSVI constant()
```
    Returns a reference to an immutable instance with the same data that this instance of ItemPSVI currently has.
  - isConstant
```
boolean isConstant()
```
    Returns true if this specific instance of ItemPSVI is immutable, otherwise false.
  - getValidationContext
```
String getValidationContext()
```
    The nearest ancestor element information item with a [schema information] property (or this element item itself if it has such a property). For more information refer to element validation context and attribute validation context .
  - getValidity
```
short getValidity()
```
    [validity]: determines the validity of the schema item with respect to the validation being attempted. The value will be one of the constants: VALIDITY_NOTKNOWN, VALIDITY_INVALID or VALIDITY_VALID.
  - getValidationAttempted
```
short getValidationAttempted()
```
    [validation attempted]: determines the extent to which the schema item has been validated. The value will be one of the constants: VALIDATION_NONE, VALIDATION_PARTIAL or VALIDATION_FULL.
  - getErrorCodes
```
StringList getErrorCodes()
```
    [schema error code]: a list of error codes generated from the validation attempt or an empty StringList if no errors occurred during the validation attempt.
  - getErrorMessages
```
StringList getErrorMessages()
```
    A list of error messages generated from the validation attempt or an empty StringList if no errors occurred during the validation attempt. The indices of error messages in this list are aligned with those in the [schema error code] list.
  - getSchemaNormalizedValue
```
String getSchemaNormalizedValue()
```
    Deprecated.
    Use getSchemaValue().getNormalizedValue() instead
    
    [schema normalized value]: the normalized value of this item after validation.
  - getActualNormalizedValue
```
Object getActualNormalizedValue()
                         throws XSException
```
    Deprecated.
    Use getSchemaValue().getActualValue() instead
    
    [schema normalized value]: Binding specific actual value or null if the value is in error.
    
    Throws:
    
    XSException - NOT_SUPPORTED_ERR: Raised if the implementation does not support this method.
  - getActualNormalizedValueType
```
short getActualNormalizedValueType()
                            throws XSException
```
    Deprecated.
    Use getSchemaValue().getActualValueType() instead
    
    The actual value built-in datatype, e.g. STRING_DT, SHORT_DT. If the type definition of this value is a list type definition, this method returns LIST_DT. If the type definition of this value is a list type definition whose item type is a union type definition, this method returns LISTOFUNION_DT. To query the actual value of the list or list of union type definitions use itemValueTypes. If the actualNormalizedValue is null, this method returns UNAVAILABLE_DT.
    
    Throws:
    
    XSException - NOT_SUPPORTED_ERR: Raised if the implementation does not support this method.
  - getItemValueTypes
```
ShortList getItemValueTypes()
                     throws XSException
```
    Deprecated.
    Use getSchemaValue().getListValueTypes() instead
    In the case the actual value represents a list, i.e. the actualNormalizedValueType is LIST_DT, the returned array consists of one type kind which represents the itemType . For example:
    <simpleType name="listtype"> <list itemType="positiveInteger"/> </simpleType> <element name="list" type="listtype"/> ... <list>1 2 3</list>
    The schemaNormalizedValue value is "1 2 3", the actualNormalizedValueType value is LIST_DT, and the itemValueTypes is an array of size 1 with the value POSITIVEINTEGER_DT.
    If the actual value represents a list type definition whose item type is a union type definition, i.e. LISTOFUNION_DT, for each actual value in the list the array contains the corresponding memberType kind. For example:
    <simpleType name='union_type' memberTypes="integer string"/> <simpleType name='listOfUnion'> <list itemType='union_type'/> </simpleType> <element name="list" type="listOfUnion"/> ... <list>1 2 foo</list>
    The schemaNormalizedValue value is "1 2 foo", the actualNormalizedValueType is LISTOFUNION_DT , and the itemValueTypes is an array of size 3 with the following values: INTEGER_DT, INTEGER_DT, STRING_DT.
    Throws:
    
    XSException - NOT_SUPPORTED_ERR: Raised if the implementation does not support this method.
  - getSchemaValue
```
XSValue getSchemaValue()
```
    If this item has a simple type definition or a complex type with simple content, then return the value with respect to the simple type. If this item doesn't have a simple-typed value, the behavior of this method is not specified.
  - getTypeDefinition
```
XSTypeDefinition getTypeDefinition()
```
    [type definition]: an item isomorphic to the type definition used to validate the schema item.
  - getMemberTypeDefinition
```
XSSimpleTypeDefinition getMemberTypeDefinition()
```
    [member type definition]: 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 type definition with {variety} union, then an item isomorphic to that member of the union's {member type definitions} which actually validated the schema item's normalized value.
  - getSchemaDefault
```
String getSchemaDefault()
```
    [schema default]: the canonical lexical representation of the declaration's {value constraint} value. For more information refer to element schema default and attribute schema default.
  - getIsSchemaSpecified
```
boolean getIsSchemaSpecified()
```
    [schema specified]: if true, the value was specified in the schema. If false, the value comes from the infoset. For more information refer to element specified and attribute specified.
