 *
 * Revision 1.4  2003/11/06 15:30:04  neilg
 * first part of PSVI/schema component model implementation, thanks to David Cargill.  This covers setting the PSVIHandler on parser objects, as well as implementing XSNotation, XSSimpleTypeDefinition, XSIDCDefinition, and most of XSWildcard, XSComplexTypeDefinition, XSElementDeclaration, XSAttributeDeclaration and XSAttributeUse.

 *
 * Revision 1.2  2003/10/10 18:37:51  neilg
 * update XSModel and XSObject interface so that IDs can be used to query components in XSModels, and so that those IDs can be recovered from components
