 * some indices in the PSVIAttributeList were 1 off
 *
 * Revision 1.5  2003/12/20 06:19:38  neilg
 * store name/namespace of corresponding attribute in PSVIAttributeList; not all PSVIAttributes have XSAttributeDeclarations
 *
 * Revision 1.4  2003/12/15 17:23:48  cargilld
 * psvi updates; cleanup revisits and bug fixes
 *
 * Revision 1.3  2003/11/26 16:20:37  neilg
 * more complete implementation of PSVIAttributeList; remove some problematic const-ness
 *
 * Revision 1.2  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 1.1  2003/09/16 14:33:36  neilg
 * PSVI/schema component model classes, with Makefile/configuration changes necessary to build them
