I agree that usability is the main problem from my user viewpoint. Of the
potential solutions that Michael has offered below, I am most partial to option
(a) and secondarily to (b). For my needs, it would most useful if the scope is
the entire XQuery, as in option (a), but I can imagine how in other use cases
it may be desirable to switch the default namespace, such as in a specialized
local function, which makes option (b) or (c) appealing.
