XQuery and databases - XQuery 2.0

[David A. Lee]

Not sure about a "standard" but the top DB vendors have done this 
already years ago

Oracle:
http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14259/xdb13gen.htm#i1027254

MS/SQL
http://msdn.microsoft.com/en-us/library/aa286527.aspx

DB2
http://www.ibm.com/developerworks/db2/library/techarticle/dm-0603saracco2/

But if you think SQL is incomprehensible, take a gander at what you have 
to do with these (above) implementations to get XML out ....

Give me pure XQuery any day :)
