All Implemented Interfaces:

IDContextProvider2, IVerifier, org.iso_relax.verifier.VerifierHandler, org.relaxng.datatype.ValidationContext, ContentHandler, DTDHandler

public class IDConstraintChecker
extends Verifier

Verifier with XML Schema-related enforcement.

This class can be used in the same way as Verifier. This class also checks XML Schema's identity constraint.
