This thread seemed to be moving towards a consensus.  Is anyone
planning to submit a contribution at Monterey? Pete? Paul?

Since the developing consensus seemed to be that H.225.0 protocol
identifier also identifies the version of H.323, I would like to
add a provision that in the absence of any H.245 protocol identifier,
that there be an implied linkage between H.323 version and H.245

That is, if any ASN.1 structure defined in H.245 is received prior
to reception of an H.245 protocol identifier, the H.245 version
used shall be that which is explicitly required by the H.323 version
identified by the H.225.0 protocol identifier in use.  This would
apply to an OLC structure in fastStart for example.
