Hi Paul
Everything looks OK with me except the very 1st change.
Specifically the empty h323-message-body element for non call related Q.931
The empty h323-message-body does not allow to add tokens to the FACILITY
message so it cannot be authenticated and its integrity cannot be checked.
My proposal is to change wording here to allow non empty h323-message-body
in the case security is required

H.323 Experts,
I have attached a document that contains the complete list of corrections
for H.225.0v4 and H.323v4, with differences against the decided text, that
we have discussed on the mailing list this past week.
I would like all interested parties to review these changes.
I am open to changing the wording, but I would like to get consensus on
making these changes.  I have asked the TSB to see if we can make these
corrections prior to the publication of the documents.  If so, I want to
have the support of everyone to make these corrections.  I don't believe
that any of these issues should be contentious, but without these
corrections, I'm afraid that many more questions and interoperability
problems will arise.
If it turns out that we cannot update the approved text before publication,
I plan to submit this document (or a modified version with comments I
receive from you) to the next meeting in March.  Personally, I'd rather
correct the Recommendation before publication, rather than adding this to
the Implementers Guide.
