Why do you think an xsl:apply-templates would need to examine your 
entire db (even if it could)? Your uri resolver could grab what you need 
to return to the transformation.

Heck, you could form some XQuery string in XSLT 1.0, send it to a uri 
resolver (through document()), which then does the xquery, then returns 
the result back to the transformation so you can apply-templates.
