[C2] XSLT transform error messages
A request for the C2 developers:
*Please* find a way to send back a reasonable error message when there is a
problem with a stylesheet. The generic "Exception in creating Transform
Handler" (below) is sooooo unhelpful. It doesn't give any clue as to the
nature of the problem, which is often subtle. Surely the XSLT transform
classes have better error reporting that can be passed on?
Thanks,
Christopher

What version of Cocoon are you using?
Presently, if all goes as intended, you should get the correct
exception, and also the row and column of the problem.
Please send me a testcase that fails on latest 2.0.3 CVS branch and I'll
personally look into it.
