  Basically you get the error in the XPath interpretor. All one get
there is the XPath evaluation context, and the data used have been 
generated when the XPath expressions of the XSLT have been compiled
in the early XSLT compilation. Maybe there is a way to plug the
informations on the XSLT location in the XPath context, or capture
libxml2 generated errors from libxslt (or xsltproc) and try to
give back the current context. Send me a sample example reproducing
the problem with xsltproc, and i will try to look, but don't hold your
breath :-)
