Sure, that will be nice.

You had me at Filter (and maybe Sort). I might be conflating Filter  
and Partition -- what is the difference?

I don't want Style in XQuery. Use XQuery to just gather up the things  
wanted and needed. That is why I think XSL running natively on the XML  
DB is important. Don't convert the XQuery result into a Source needed  
by an XSL processor on top of the DB, just continue on with the XQuery
