XQuery in both theory (the spec) and practice (e.g. Microsoft's stuff that 
Dare was showing at XML 2002) operates off a data model (aka Infoset, more 
or less) that encompasses both XML and the relational model.  Since it 
incorporates XPath by reference, XPath is therefore a globally applicable 
addressing mechanism for data that can be represented in the 
datamodel/infoset.  What's wrong with that logic?

I don't know how to reconcile that statement with the popularity of 
XPath/XSLT and the widespread enthusiam for the *basic idea* of XQuery (net 
the mumbo jumbo we like to complain about, which has more to do with the 
PSVI than the Infoset).
