This is what I meant by 'running natively' on an XML DB:

Most basically because XQuery, running natively on an XML DB, does not  
need to serialize out a DOMish object to work on. XSLT does.

Say you want to do a transformation using data from your entire DB or  
files. For XSLT you would need to load all documents into memory. With  
XQuery on an XML DB, you don't.

I would love to have XSL run natively.
