| If my suggested fix for bug #407810 in xmlproc is correct, it would
| be trivial to fix.  If it's not, this might be more difficult to
| fix.

The fix turned out to be wrong, but luckily the problem wasn't very
hard to fix.

I've fixed it now both in my CVS tree and in the PyXML CVS tree.

I've also done most of the hard work in cleaning up the test suite and
making it read for a move to the PyXML test suite. I hope to be able
to do the rest soon.
