- * sane_include
- *
- * Revision 1.14 2001/05/11 13:24:58 tng
- * Copyright update.
- *
- * Revision 1.13 2001/05/03 16:00:25 tng
- * Schema: samples update with schema
- *
- * Revision 1.12 2000/10/10 23:55:58 andyh
- * XMLFormatter patch, contributed by Bill Schindler. Fix problems with
- * output to multi-byte encodings.
- *
- * Revision 1.11 2000/07/25 22:41:32 aruna1
- * Char definitions in XMLUni moved to XMLUniDefs
- *
- * Revision 1.10 2000/06/17 01:58:06 rahulj
- * Now output the PI's with no space between ? and target.
- *
- * Revision 1.9 2000/05/31 23:58:19 rahulj
- * Needed an explicit char* cast to get it working under Solaris.
- *
- * Revision 1.8 2000/04/07 23:25:53 roddey
- * A couple more tweaks of the event handler output.
- *
- * Revision 1.7 2000/04/06 19:09:51 roddey
- * Some more improvements to output formatting. Now it will correctly
- * handle doing the 'replacement char' style of dealing with chars
- * that are unrepresentable.
- *
- * Revision 1.6 2000/04/05 00:20:32 roddey
- * More updates for the low level formatted output support
- *
- * Revision 1.5 2000/03/28 19:43:11 roddey
- * Fixes for signed/unsigned warnings. New work for two way transcoding
- * stuff.
- *
- * Revision 1.4 2000/03/02 19:53:49 roddey
- * This checkin includes many changes done while waiting for the
- * 1.1.0 code to be finished. I can't list them all here, but a list is
- * available elsewhere.

- * Revision 1.3 2000/02/11 03:05:35 abagchi
- * Removed second parameter from call to StrX constructor
- *
- * Revision 1.2 2000/02/06 07:47:24 rahulj
- * Year 2K copyright swat.
