  Right xmlXPathEval implements the XPath 1.0 Language
     http://www.w3.org/TR/xpath
And that construct is not allowed by that language.

  Maybe, maybe not. It doesn't matter anyway.

  $any$ is not part of the XPath syntax. XSLT uses the XPath syntax, 
the syntax you're showing cannot be handled by libxml2 XPath engine nor by
libxslt XSLT 1.0 implementation.
