I'm not directly participating for Oracle, but I've forwarded your
question to our rep who is. Likely both XML Schema and XPath
would play a role in extending SQL99 to more elegantly handle XML,
but it's too early to say at this point what SQLX "looks" like.

We're certainly participating in both. RDBMS vendors and ORDBMS
vendors have spent years tuning the query optimizers and query-rewriting
capabilities of their engines. If new query syntaxes become
popular in the customer base, I'd imagine what lots of the existing
database vendors want to make sure is that any query in a new
syntax could be efficiently rewritten into a query that their
existing engines and optimizers can process well. With our heavy
investment into both SQL- and XML-related technologies, it makes
sense for us to participate in both.

It's being done as part of the ANSI SQL standards activity.
My uneducated guess is that any member of ANSI could be a
