## org.apache.xerces.validators.schema.identity
Class IDValue

    java.lang.Object
      |
      +--org.apache.xerces.validators.schema.identity.IDValue

public class IDValue
extends java.lang.Object

Stores a value associated with a particular field of an identity constraint that has successfully matched some string in an instance document. This class also stores the DatatypeValidator associated with the element or attribute whose content is the string in question; this must be done here because type determination is dynamic.

This class also makes it its business to provide functionality to determine whether two instances are duplicates.
