[omniORB] Object Id and POA reference

[Brenneis, Steve]

Thanks for the quick response, David.

This leads me to a little more esoteric follow-up. Since the method of
encapsulating these two components is not specified, would it be allowable
for an ORB implementation to accomplish this in another way (e.g. private
tagged profiles)? If so, wouldn't this represent a potential
interoperability issue since GIOP specifies that private profiles, for
instance, are allowed, but clients and servers may not rely on their
presence or absence in any ORB or Request invocation?

There is a concrete reason behind these abstract questions. I am trying to
identify potentials for interoperability failures between ORBs operating at
various levels of CORBA 2.x compliance. I have always been able to trust the
omniORB team to implement in the most standard way, so I am using omniORB as
my baseline for this evaluation.

Thanks again for the help.
