what do you want the xslt to do?

given any xml, say

<x>
  <y>zzz</y>
  <y>zzz</y>
</x>

then adding an xsl:version attribute

<x xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
  <y>zzz</y>
  <y>zzz</y>
</x>

makes a valid XSLT stylesheet that given (any) input will generate the XML
file that you started with.

Perhaps though you want something more like Ken's recent paper in
extreme
http://www.idealliance.org/papers/extreme/Proceedings/html/2005/Holman01/EML2005Holman01.html
which generates XSLt from some annotated XMl files.
