I've been looking at this more. Here's the steps (I think)

- add a libxslt_xsltCompare(PyObject *a, PyObject *b)

- add python API for the above (alter libxslt-python-api.xml)

- add a new class in libxsl.py: xsltCore with a __cmp__ or an __eq__
  that calls libxslt_xsltCompare

- change generator.py's classes_ancestor map to include stylesheet and
  transformCtxt as xsltCore objects


I'm still unclear as to how libxslt_xsltCompare might work generically
for stylesheet and transformCtxt objects. It might be that I need 2
different parent classes just to perform this trick.


Someone (Daniel?) verify this isn't mad?
