Let the XSLT script detect the name and release of the

When I apply an XSLT script on an input.xml I want to output at first a node (into 
the result,xml) which shows the used XSLT processor and his release.

So the putput should be something like

<?xml .....>
   <usedxsltproc>Saxon v9.1.0.7</usedxsltproc>
   <otherstuff>
     .....
   </otherstuff>


Is this somehow possible?
