That's true, though I think as more databases move into a web services mode,
the advantage of the anonymous data store becomes a moot point. You see this
in the collections() function in XPath2, which loads in nodal connections
from across a wide variety of sources, so long as those sources can be
specified as URLs. Granted, with XQuery you can create standalone filters
for database queries, but  the question I have here is whether this feature
will necessarily dislodge the generations of SQL programmers who are less
inclined to use yet another query language.
