Rich,
I guess that I misunderstood what you were saying. I agree that your proposed solution is the only practical one at this time.
As to Q.932, etc. I think that it would be best to keep all references to the versions in v2 for the same reason as for Q.931.

Hi Bob,
I just want to remind everyone that we agreed in Osaka not to update the Q.931 cross-references, but instead to revert the parent reference to Q.931 (1993) so we (I) wouldn't have to update and verify all of the table references, etc.
However, when I was about to make that change, I noticed that there were references to 1998 versions of other standards (Q.932, Q.850) also, and I was concerned that these other standards might reference the 1998 version of Q.931, so we would have a synchronization problem of another kind. That's why I didn't make the change, and noted this as an open issue.
I also have some concern about referencing a standard that is no longer published.
My preference would be to leave the parent reference as Q.931 (1998) and update the semi-infinite number of cross-references.
I agree the inconsistency has to be corrected. BTW, this also existed in v2.

On of the open issues is the correct version of Q.931 should be referenced in H.225.0 and H.323. When v3 was decided, they was updated to reference Q.931(1998) instead of Q.931(1993). This is a discussion of the impact of this change and how to resolve the problems.
- H.225.0 and Q.931 include a semi-infinite number of references to table,
figures and sections of Q.931. V3 still references the 1993 items even though the parent reference is 1998. It is possible to update all the detailed references or to return the parent reference to 1993. Either way they must be consistent.
- Q.931(1998) introduced a number of changes from the 1993 version. If we
update v4 to consistently reference 1998, do we want to automatically include all the changes in Q.931?
- If we do accept, by default, the changes to Q.931, do any of these
changes
conflict with the ASN.1 coding that we use? If so, how is this resolved?
However this problem is resolved, it must be consistent within H.323v4 and H.225.0v4.
