thanks for your response.
This is a result of the name change from CCITT to ITU-T. So,
different documents use different names depending on when they were
published. The bits on the wire are not impacted, so I have never
worried about it.
I am fully aware of the history, but that change is back quite
a couple of years now. IIRC, that must have been more than 15 years
ago; in particular, the X.680 1994 Edition (== ISO/IEC 8824-1:1995)
already specified the new name(s) as the primary identifier(s).
My arguments are primarily:
o avoiding possible confusion;
o making new documents easier to read for newcomers not aware
of the history of the ITU-T;
o self-consistency within new documents (a major goal of RFC Editor
o consistency within the set of related document revisions
currently in progress;
o using current terminology and names in new documents;
o referring to the new name when making citations of the X.680
series of IUT-T Recommendations (and that's the way SMIME and
PKIX are moving forward).
