 * $Log: IGXMLScanner.hpp,v $
 * Revision 1.18  2004/01/29 11:46:30  cargilld
 * Code cleanup changes to get rid of various compiler diagnostic messages.
 *
 * Revision 1.17  2003/11/28 19:54:31  knoaman
 * PSVIElement update
 *
 * Revision 1.16  2003/11/28 05:13:29  neilg
 * Fix state-ful duplicate attribute detection when the integrated
 * scanner is in use and namespaces are off.  Also, implement
 * change to PSVIHandler interface to remove prefix passing.
 *
 * Revision 1.15  2003/11/27 22:52:37  knoaman
 * PSVIElement implementation
 *
 * Revision 1.14  2003/11/27 06:10:31  neilg
 * PSVIAttribute implementation
 *
 * Revision 1.13  2003/11/26 16:20:00  knoaman
 * Store XSModel.
 *
 * Revision 1.12  2003/11/24 05:09:38  neilg
 * implement new, statless, method for detecting duplicate attributes
 *
 * Revision 1.11  2003/10/22 20:22:30  knoaman
 * Prepare for annotation support.
 *
 * Revision 1.10  2003/09/22 19:51:41  neilg
 * scanners should maintain their own pools of undeclared elements, rather than requiring grammars to do this.  This makes grammar objects stateless with regard to validation.
 *
 * Revision 1.9  2003/08/14 02:56:41  knoaman
 * Code refactoring to improve performance of validation.
 *
 * Revision 1.8  2003/07/10 19:47:23  peiyongz
 * Stateless Grammar: Initialize scanner with grammarResolver,
 *                                creating grammar through grammarPool
 *
 * Revision 1.7  2003/05/22 02:10:51  knoaman
 * Default the memory manager.
 *
 * Revision 1.6  2003/05/15 18:26:29  knoaman
 * Partial implementation of the configurable memory manager.
 *
 * Revision 1.5  2003/03/07 18:08:58  tng
 * Return a reference instead of void for operator=
 *
 * Revision 1.4  2003/01/29 19:59:35  gareth
 * we now detect when elements and attributes are validated/ the result of the validation and store that information.
 *
 * Revision 1.3  2003/01/15 15:49:49  knoaman
 * Change constant declaration name to match its value.
 *
 * Revision 1.2  2003/01/13 16:30:18  knoaman
 * [Bug 14469] Validator doesn't enforce xsd:key.
 *
 * Revision 1.1  2002/12/04 02:05:25  knoaman
 * Initial checkin.
