* Revision 1.4 2002/12/09 13:12:12 tng
* Fix compilation error.

committed
* 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.
