This is not the official official comments list -- I read it when I
can, but I don't always manage to read every post -- _please_ post
issues with the RECs or the errata to www-xml-schema-comments@w...
as well as here.

This is a corner case, hard to be sure about -- the REC was actually
contradictory as it stood, with one clause specifying one form, and
another clause a conflicting form.  In that case, there are _no_
non-breaking fixes, at least in principle, and we went with what we
believed was the majority of existing usage in practice -- are you
aware of any _deployed_ schemas using the --MM-- form?

On balance I support the judgement call that this change should not
have resulted in a namespace change -- the REC was (by accident)
contradictory, we agreed what we meant, we've brought the REC into
line with that agreement.
