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

But if you think SQL is incomprehensible, take a gander at what you
have to do with these (above) implementations to get XML out ....<br>
<br>
Give me pure XQuery any day :)<br>

type="cite">I had heard that future versions of the SQL standard are
to bring XML in to SQL -- basically make non-validated XML nodes as
valid column types and add intra-XML indexing. This was quite a while
ago that I heard it, but it was delivered by a reputable source. Seems
like these two language have huge overlap and can eventually be
replaced by a single query language.<br>
<br>
(Besides, SQL is so incomprehensible for even modestly-sized queries,
it would be great to replace it with something a bit more
understandable such as XQuery; not to mention the legions of vendor
specifics and incompatibilities...)<br>

Another option, eXist, provides a XQuery Extenesion module for SQL<br>
connections and queries. I would like to see the concepts from there<br>
eventually it into the EXPath/EXQuery efforts<br>
