This depnds on the XQuery engine you use. E.g. for my own Web site,
the Java-based XQuery engine I use is Qizx, and it does support a
way to connect to a erlational database (I'm assuming this is
what you are asking here?), but the zero-dollar version of that
product is limited to a database of only one gigabyte of XML.

You can look at http://www.w3.org/XML/Query - I admit I'm not very
good at publishing news items, but I do try: there will be one
later today :-)
