I'm not aware of anyone who has approached teaching the language from this
angle: many tutorials assume ignorance of XPath 1.0, let alone 2.0. This
reflects that fact that many people seem to be coming to XQuery without
previous XPath experience (in fact, a lot of them come with no real XML
experience).
The differences are essentially:
1. FLWOR expressions
2. node construction expressions
3. function declarations
4. the Query Prolog
(2) and (3) are extremely similar to their XSLT 2.0 equivalents; (4) is
largely administrivia; so the real meat is (1) - FLWOR expressions. There
are a few tutorials on FLWOR, for example my article at
