* Revision 1000.1  2003/11/21 18:21:07  gouriano
* PRODUCTION: UPGRADED [ORIGINAL] Dev-tree R1.15
*
* Revision 1.15  2003/11/20 14:32:11  gouriano
* changed generated C++ code so NULL data types have no value
*
* Revision 1.14  2002/11/19 19:47:50  gouriano
* added support of XML attributes of choice variants
*
* Revision 1.13  2002/11/14 21:07:11  gouriano
* added support of XML attribute lists
*
* Revision 1.12  2002/10/15 13:53:08  gouriano
* use "noprefix" flag
*
* Revision 1.11  2001/06/11 14:34:58  grichenk
* Added support for numeric tags in ASN.1 specifications and data streams.
*
* Revision 1.10  2000/08/25 15:58:45  vasilche
* Renamed directory tool -> datatool.
*
* Revision 1.9  2000/06/16 16:31:12  vasilche
* Changed implementation of choices and classes info to allow use of the same classes in generated and user written classes.
*
* Revision 1.8  2000/05/03 14:38:10  vasilche
* SERIAL: added support for delayed reading to generated classes.
* DATATOOL: added code generation for delayed reading.
*
* Revision 1.7  2000/04/17 19:11:04  vasilche
* Fixed failed assertion.
* Removed redundant namespace specifications.
*
* Revision 1.6  2000/04/12 15:36:39  vasilche
* Added -on <namespace> argument to datatool.
* Removed unnecessary namespace specifications in generated files.
*
* Revision 1.5  2000/04/07 19:26:07  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 1.4  2000/03/17 16:47:38  vasilche
* Added copyright message to generated files.
* All objects pointers in choices now share the only CObject pointer.
*
* Revision 1.3  2000/03/07 14:06:04  vasilche
* Added generation of reference counted objects.
*
* Revision 1.2  2000/02/11 17:09:26  vasilche
* Removed unneeded flags.
*
* Revision 1.1  2000/02/01 21:46:14  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 1.5  2000/01/10 19:46:47  vasilche
* Fixed encoding/decoding of REAL type.
* Fixed encoding/decoding of StringStore.
* Fixed encoding/decoding of NULL type.
* Fixed error reporting.
* Reduced object map (only classes).
*
* Revision 1.4  1999/12/01 17:36:28  vasilche
* Fixed CHOICE processing.
*
* Revision 1.3  1999/11/16 15:41:17  vasilche
* Added plain pointer choice.
* By default we use C pointer instead of auto_ptr.
* Start adding initializers.
*
* Revision 1.2  1999/11/15 19:36:21  vasilche
* Fixed warnings on GCC
