The model is that XSLT (or XQuery) is running over instances of
the XPath 2 data model.  Implementations exist that project
relational database tables so that they appear to be XML documents,
so that there's no special code "grabbing" data.

Yes, you could do that. It's a good demonstration of the difference
in focus between XSLT and XQuery that I was trying to illustrate.
