* Revision 1000.1  2004/04/12 17:16:23  gouriano
* PRODUCTION: UPGRADED [CATCHUP_003] Dev-tree R1.6
*
* Revision 1.6  2004/02/25 19:45:48  gouriano
* Made it possible to define DEFAULT for data members of type REAL
*
* Revision 1.5  2003/10/02 19:39:48  gouriano
* properly handle invalid enumeration values in ASN spec
*
* Revision 1.4  2003/06/16 14:40:15  gouriano
* added possibility to convert DTD to XML schema
*
* Revision 1.3  2000/12/15 15:38:36  vasilche
* Added support of Int8 and long double.
* Added support of BigInt ASN.1 extension - mapped to Int8.
* Enum values now have type Int4 instead of long.
*
* Revision 1.2  2000/04/07 19:26:15  vasilche
* Added namespace support to datatool.
* By default with argument -oR datatool will generate objects in namespace
* NCBI_NS_NCBI::objects (aka ncbi::objects).
* Datatool's classes also moved to NCBI namespace.
*
* Revision 1.1  2000/02/01 21:46:25  vasilche
* Added CGeneratedChoiceTypeInfo for generated choice classes.
* Removed CMemberInfo subclasses.
* Added support for DEFAULT/OPTIONAL members.
* Changed class generation.
* Moved datatool headers to include/internal/serial/tool.
*
* Revision 1.9  1999/12/29 16:01:53  vasilche
* Added explicit virtual destructors.
* Resolved overloading of InternalResolve.
*
* Revision 1.8  1999/11/19 15:48:11  vasilche
* Modified AutoPtr template to allow its use in STL containers (map, vector etc.)
*
* Revision 1.7  1999/11/15 19:36:22  vasilche
* Fixed warnings on GCC
*
