At XML 2001, four members of the Query WG were asked when they thought we 
should try to go to CR with XQuery 1.0, and all four basically answered 
this summer. That does not include updates, but it does include joins and 
strong typing.

What I think we should do for updates, and what I *am* doing, is to prepare 
a proposal and let the XML Query WG respond to it. I am doing this together 
with other vendors who plan to implement updates.

I am all ears on this. Personally, I would think it would be particularly 
interesting to hear feelings about:

1. An XQuery 1.0 CR this summer, with a separate CR for updates six months 
2. An XQuery 1.0 CR a year from now including updates.

This is really the crucial question. Personally, I do not think that 
waiting a year or two for updates would be a good option.

I personally think this would create more long-term problems.
