  it's really not expected to be used on its own. There is serious
dependancies with internal data like caching informations dependant
on the XSLT processing itself.

  most headers outside of xslt.h are kind of private, they are here to
allow hacking but I can't really spend much time supporting users of 
those features. You can copy the XSLT pattern.c module and hack on it
to fit your needs for example.
  What I can support is the streaming subset in libxml/pattern.h or
the full XPath queries from libxml/xpath.h those are really intended to
be public APIs.
