Paul,
I think that consistence of references between H.323 and H.225.0 would be a
good thing. It would not be good to gain a feature or code point in H.323
that is not supported by H.225.0.

Rich,
Hmmm... editors in disagreement? Perhaps I should read before I post :-).
OK, if Rich is willing to make this change, I suppose I can do the same for
H.323, though I would guess it is much less work. I took a quick scan and
there do not appear to be any issues in H.323, per se, that require
attention in order to make this change. Is anyone aware of any issues?
