Examples of org.apache.xerces.impl.dv.XSSimpleType

org.apache.xerces.impl.dv.XSSimpleType
This interface XSSimpleType represents the simple type definition of schema component and defines methods to query the information contained. Any simple type (atomic, list or union) will implement this interface. It inherits from XSTypeDecl. @author Sandy Gao, IBM @version $Id: XSSimpleType.java,v 1.10 2002/10/25 16:42:30 sandygao Exp $
