- * Revision 1.4 2002/12/09 13:12:12 tng
- * Fix compilation error.
- *
- * Revision 1.3 2002/12/09 09:57:27 gareth
- * Fixed compile error by adding private member. Not very efficient. Should be looked at again.
- *
- * Revision 1.2 2002/11/04 15:11:38 tng
- * C++ Namespace Support.
- *
- * Revision 1.1.1.1 2002/02/01 22:22:23 peiyongz
- * sane_include
- *
- * Revision 1.3 2000/07/21 03:31:42 andyh
- * Improved (but still weak) http access by the parser.
- *
- * Revision 1.2 2000/03/22 00:58:12 rahulj
- * Now we throw exceptions when errors occur.
- * Simplified code based on assumption that calling
- * function will allocate enough storage to store the
- * incoming data.
- *
- * Revision 1.1 2000/03/20 23:48:51 rahulj
- * Added Socket based NetAccessor. This will enable one to
- * use HTTP URL's for system id's. Default build options do
- * not use this NetAccessor. Specify the '-n socket' option
- * to 'runConfigure' to configure Xerces-C to use this new
- * feature. The code works under Solaris 2.6, Linux, AIX
- * and HPUX 11 with aCC.
- * Todo's: enable proper error handling.
