        xupdate2xsl: Translate XML document from namespace 'xupdate' to 'xsl'.
        
        Purpose of this XML Stylesheet is to implement a set of templates 
        to translate XUpdate lingo into an intermediate xslt stylesheet 
        which actually performs the update to the original xml document
        in a second step.
        
        The required glue code - written in Perl - is available in module 
        XML::XUpdate::XSLT. Please have a look at this in order to write
        code to use this stylesheet from other language bindings.

        Please have a look at the XUpdate specs and associated resources:
