   o What about proper encoding? (ISO-8859-1 or UTF-8)
   o Is it possible to create the required "xsl_template.xml" at runtime via XSL itself?
   o Cache contents of external files (*.xml). Performance!
   o Can exception / error-code handling be improved somehow?
       Esp.: It would be interesting, if the XUpdate payload actually could be applied, or not...
+  o <xupdate:if>, etc.
