Well, the SQLX group seems to moving partiulcarly slowly. In the past year all
I've seen come from them are a press release or two and a fairly cumbersome
document that describes mappings from SQL types to XML types
which seems to contain some information based pre-recommendation version XML
I assume that since IBM and Oracle are members of SQLX, we're going to see the
creation of an XMLType in SQLX and extensions to SQL that allow one to perform
XPath queries over XMLType columns. Since MSFT and Sybase are also on the SQLX
board, I wonder if they will adopt similar a XMLType construct (I know that
SQL Server has none but know not off Sybase) and if so whether they'll stick
to alowing queries in a subset of Xpath 1.0 / Xpath 2.0 or even XQuery?
Reminds me of OODBMSs and RDBMSs all over again with all the object-relational
hoopla.that sprung up around that.
 Document refers to xsd:timeDuration and xsd::timeInstant types.

I will not grow a goatee. In the old days they made you look diabolic. Now
they just make you look like a disaffected member of Generation X.
