 * fix for bug 25118; thanks to Jeroen Witmond

 *

 * Revision 1.6  2003/11/21 22:34:45  neilg

 * More schema component model implementation, thanks to David Cargill.

 * In particular, this cleans up and completes the XSModel, XSNamespaceItem,

 * XSAttributeDeclaration and XSAttributeGroup implementations.

 * Thanks to David Cargill.

 *

 * 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.
