Well, the nice thing about XML:DB is that I think it's far more of a meritocracy than most standards incubators.

Wow.  Where have you been hiding this gem?

This looks quite well considered, and certainly fits better into the XAPI than XUpdate.

One problem I see is that it will be hard to implement, and even harder to optimize (I'm working on an XUpdate processor that can handle a decent subset of requests within a single SAX stream).

But ease of implementation is only part of the story.  (out of curiousity, has SiXDML been implemented?)  You've given me some food for thought.

I personally am *very* tempted, but I'm already drowning in mailing lists, and I'm not sure I'd realistically be able to contribute much to such an effort in the near term.  Please do keep the announcements coming, though.

Well, if you're ever about to be fired for your temerity in working on useful, practical solutions for the XML community, let us know.  I'm sure we can round up a virtual candlelight vigil to better inform your employer  :-).
