+  Simple transform of Solr query response into Solr Update XML compliant XML.
+  When used in the xslt response writer you will get UpdaateXML as output.
+  But you can also store a query response XML to disk and feed this XML to
+  the XSLTUpdateRequestHandler to index the content. Provided as example only.
