         The name was chosen to reflect the draft that it
models objects for. The working group accepted the document
named as it is.

         Please point out where you think there are deficiencies and
how you would like us to resolve them.

         I don't understand how a conformance group can
help in this regard. Conformance groups are used to
point out which objects must be supported and which
are optional (and under what circumstances).

         Will do.

         Okay.
