I've set things up so that my document path includes the language code
(e.g. 'en_US') as the first part of the path under
src/documentation/content/xdocs.  For example,
src/documentation/content/xdocs/en_US/mydocument.xml would be the
starting point.  The question is what the $path variable will contain
- if it's just "en_US/mydocument.xml" my job is easy.  If it could be
"en_US\mydocument.xml" on Windows and "en_US/mydocument.xml" on Unix
it's a bit harder.   But if it is the absolute path xsl expressions
aren't going to help me and I'd better find a better solution.

What I'd do (and this might even make a decent general patch) is look
for the property with the language specifier first.  For example,
instead of looking for "output.pdf.fontFamily.sansSerif" first, I'd
look for "output.pdf.fontFamily.sansSerif.en_US" first, and only look
for the other if that property is not found.

So, what can I expect to see for the $path parameter?

Thanks again for your help!
