What I wrote in the previous comment that xsltCompMatchPatternList matches
XSLPattern is not true. xsltCompMatchPatternList matches a pattern as in
<xsl:template match="..."> - it find nodes for which there exist a context node
such the the pattern matches and has a limited syntax compared to XPath. That's
why there were false positives. To match XPath queries for a given context node
one has to use xmlXPathEval. I've made some patches adding it.

The XSLPattern is a Microsoft's own language probably based on a working draft
of XSL. I couldn't find a specification but the differances with XPath that I've
found about are:
  - The indexes starts from 0, not from 1
  - It compares QNames, not expanded names (that what's needed by Civ4)
  - Some tokens needs to be changed (see
http://msdn.microsoft.com/msdnmag/issues/0900/xml/figures.asp#fig6)
  - It has support to work with types defined in XDR schema

Except the last point, it should be possible to rewrite an XSLPattern into an
XPath query. If we can define custom functions in should be possible to do it
without parsing the XSLPattern - only we will need to tokenize it
