- * Revision 1.15 2001/11/22 14:47:54 tng
- * Use the phrase "Grammar" instead of "Validator" in EnumVal and SEnumVal Description.
- *
- * Revision 1.14 2001/10/25 15:18:33 tng
- * delete the parser before XMLPlatformUtils::Terminate.
- *
- * Revision 1.13 2001/10/19 19:02:42 tng
- * [Bug 3909] return non-zero an exit code when error was encounted.
- * And other modification for consistent help display and return code across samples.
- *
- * Revision 1.12 2001/05/11 13:24:54 tng
- * Copyright update.
- *
- * Revision 1.11 2001/04/19 18:16:46 tng
- * Schema: SchemaValidator update, and use QName in Content Model
- *
- * Revision 1.10 2001/03/21 21:55:57 tng
- * Schema: Add Schema Grammar, Schema Validator, and split the DTDValidator into DTDValidator, DTDScanner, and DTDGrammar.
- *
- * Revision 1.9 2000/06/12 22:07:22 rahulj
- * Correctly rejects unsupported command line options.
- *
- * Revision 1.8 2000/05/31 18:50:42 rahulj
- * Removed extraneous command line arguments.
- *
- * Revision 1.7 2000/03/03 01:29:30 roddey
- * Added a scanReset()/parseReset() method to the scanner and
- * parsers, to allow for reset after early exit from a progressive parse.
- * Added calls to new Terminate() call to all of the samples. Improved
- * documentation in SAX and DOM parsers.
- *
- * Revision 1.6 2000/03/02 19:53:40 roddey
