Does anyone know about the status of the ANSI/ISO SQL effort
to add XML support to SQL?  Looking quickly at the latest working
draft at ftp://sqlstandards.org/SC32/WG3/Progression_Documents/Informal_working_drafts/wd-xml-2001-06.pdf
I see a lot of wrestling with the mapping of SQL data types to XML Schema data types.  Is there more coming in the way of mapping SQL operations onto XML hierarchies (e.g., incorporating XPath-like expressions?), am I missing something, or what?

Or perhaps are the SQL standards people primarily interested in presenting the results of an RDBMS query in XML syntax, and not querying for XML content in a database?
