  Hum, the loader at the libxml2 level has no knowledge of the upper
layer libxslt. I'm afraid this is not simple even when working at the
C level with all the control, and probably impossible at the Python
level. The ctxt passed to the resolver is a parsing context. 
  At the C level the loader could use the new loader function

    http://xmlsoft.org/XSLT/html/libxslt-documents.html#xsltSetLoaderFunc

which then have pointers to the stylesheet context or the transformation
context. But I don't think there is bindings available at the Python level
for this yet.
