Pardon my ignorance (just joined a few days ago
and still in ROM mode), but where can I get the
complete draft?

Can't we put this under a postive response?
Perhaps with a code (eg. ala FTP) that says more information
is available. Then, it is up to the client to get this additional
information. Perhaps it just wants to know whether such
object exists or not.
(Since I have not read the requirements draft,
I don't know how the state diagram of the protocol looks like.)

I, too, am not too keen on XML-based protocols :-)
