Hi John: Thanks for your postings to the XQuery list. I enjoy your  

As an example... Ilya needs to do transactional node-level updates.  
How does he get that when XQuery has no updates specification?

XML lets me do typing using complex data types. Some XML DBs support  
XSD and some DTD while others don't do any validation.

Hope this helps.
