>The enforcement of  (a) execution and ( b) order of execution is of vital importance when writing standalone queries of extended functionality, e.g.
standalone queries opening, using and closing JDBC connections.

Then I would expect any vendor providing such extensions to provide them in
such a way that they are usable for the purpose.

There's been initial design work done on procedural extensions to XQuery (see
papers on XQueryP) which will provide semantics for extensions with
side-effects. In the meantime it's up to vendors defining such extensions to
explain to users how they should be used, and what guarantees are offered by
the implementation.
