Sorry, I should have written "SQL/XQuery" instead of "SQL". From the point of view of the discussion, XQuery is as likely to be as tightly bound to physical schemas as SQL. I was talking more of declarative messaging-style XML queries that do not implement a formal query language. Cheers, Tony. ==== Anthony B.
