           Summary: [UPD] Extend the semantics of Ordered and Unordered
                    Expressions

In the specification, "XQuery 1.0: An XML Query Language"
section 3.9 Ordered and Unordered Expressions, it specifies
the ordering mode (wrt document order) for enclosed
expressions. I would like to propose that the semantics
be extended to control the processing order of the
enclosed scope.

Besides updating of nodes, there can be other external
functions with side-effects (eg. reading from a file),
it will be desirable that the user can control the
processing order of the expressions, being ordered or 
unordered, so as to make the behaviour of updates
and calling of functions with side-effects predictable.
