One issue not addressed is what progress has the XQuery WG already made on
update syntax.  If they have already done substantial preliminary work, but
have some perceived need to produce an interim XQuery spec before that's
ready for release, it may be a duplication/fragmentation of effort to
produce a competing spec in an Oasis TC, and take just as long.  Perhaps the
WG could provide some more public information about their plans for update
language, both in terms of content and scheduling.  Perhaps they could open
up the process enough to provide a snapshot of their current straw man and
some indication of when they hope to release a solidified spec.  This will
help to determine whether an OASIS TC would be useful.  It would also allow
implementors willing to tilt at a moving target a chance to get out in front
of the spec, thus providing useful feedback for the WG.
