------- Comment #3 from cmsmcq@w3.org  2007-02-22 20:21 -------
An update on current status.  At the ftf meeting at the end of
October and beginning of November, the WG agreed that in principle
a legal schema can use any legal XPath 2.0 expression as an
assertion.  

To avoid requiring all XSD processors to implement all of
XPath 2.0, the subset defined in the spec will be retained, 
and all schema processors are required to support at least 
that subset of XPath 2.0; other processors may choose to 
support more, or all, of XPath 2.0.  Schema authors who care
more about power than interoperability will choose schema
processors accordingly; schema authors who care about
interoperability more than about power will restrict themselves
to expressions in the subset.  (Schema authors who care about
both power and interoperability will presumably just curse
the Working Group.) 

So a technical direction for resolution of this issue
has been set, although no final wording has been adopted
(and thus the decision is not yet part of the status quo
text).  A wording proposal is expected to go to the Working
Group real soon now, possibly today or tomorrow.
