  Okay, then you have a point I need to fix this !

  Extending a C based binary in a portable fashion is just hell, 
have you looked at the python wrappers for libxml2/libxslt. There is
an (nearly complete) rewrite of xsltproc in python called pyxsltproc.py
(in /usr/share/doc/libxslt-python-... if you installed libxslt-python
on a red Hat system), as well as a couple of examples on how to extend
the engine with Python written functions, that could be one solution.

 Yes, if you really want to stick to C, then yes the best is to start from
the xsltproc code and extend it with your own set of function following
the guidelines of extensions.html .

 How were you expecting initialy to extend xsltproc, if not by gluing 
in C functions? honnestly I wonder about this, there is something
which escapes me ...
