Yes, I think so.

Yes, I think this one could be more than useful, in particular
for pipeline languages. What a pity that such a definition does
not exist yet, so it could have been used by XProc. Too late

Funny, I wouldn't have thought of that one. To integrate
smoothly with an XML document, I would say the static context
should inherit the in-scope namespace bindings from the element
the query is embedded into (with "declare namespace" having
higher precedence.) Of course, experience accumulated by
languages like XPL in Orbeon is of great help here.
For the challenges part, I would think more about rewriting
XQuery grammar production rules.
