[Michael Rys] Yes. This is the prototype I refer to. Note however, that
the update language there is much behind the current state of the work.

[Michael Rys] We are debating on what to call it and whether to include
it as a required functionality.

[Michael Rys] This is combined work from some people participating in
the XML Query WG, Microsoft included. Note however, that the standard
disclaimers about no commitment to productization etc apply.
