Well, to correct the correction, I wasn't incorrect (at least not
completely).  The standards I was refering to are "ISO" standards, not
CCITT.

In the 1984 CCITT Red Books (note the 1984 and CCITT) CCITT is
publishing the Layer 4 (X.224) and Layer 5 (X.225) standards.  Also,
they are publishing the X.400 family.  X.409 is very similar to the
ISO Abstract Syntax Notations which is part of the layer 6 standard
and the rest of X.400 covers an application layer protocol, etc.  That
covers most of the bases.

Now the real clarification.  ISO and CCITT are not the same thing.  I
should have been more careful in specifying which standards body I was
referring to.  The adoption procedure within ISO is a little faster
than within CCITT.  ISO standards get approved at TC97 meetings which
happen on the order of once per year.  CCITT standards are approved at
the end of 4 year study periods.  Then there are the various national
standards bodies that all have different rules.
