  Revision 1.1.4.3  2001/08/15 10:26:09  dpg1
  New object table behaviour, correct POA semantics.

  Revision 1.1.4.2  2001/05/31 16:21:13  dpg1
  object references optionally just store a pointer to their repository
  id string rather than copying it.

  Revision 1.1.4.1  2001/04/18 17:18:19  sll
  Big checkin with the brand new internal APIs.
  These files were relocated and scoped with the omni namespace.

  Revision 1.2.2.2  2000/09/27 17:43:55  sll
  Updated to match the changes in the proxyFactory class.

  Revision 1.2.2.1  2000/07/17 10:35:50  sll
  Merged from omni3_develop the diff between omni3_0_0_pre3 and omni3_0_0.

  Revision 1.3  2000/07/13 15:25:59  dpg1
  Merge from omni3_develop for 3.0 release.

  Revision 1.1.2.3  1999/10/16 13:22:52  djr
  Changes to support compiling on MSVC.

  Revision 1.1.2.2  1999/10/04 17:08:30  djr
  Some more fixes/MSVC work-arounds.

  Revision 1.1.2.1  1999/09/22 14:26:42  djr
  Major rewrite of orbcore to support POA.

//  Of course, one can only use such an object as a CORBA::Object_ptr and
// pass it around as the type "Object" in IDL operations and attributes.
