True - I just think this should be reflected more in the documentation (even if
it is just "really nasty errors can't be trapped"), particularly in the case of
functions like this which could die on user-provided data. Similarly, I'm
guessing that Sablotron doesn't provide more debugging information but is there
any way it could be a little more informative? It's a little frustrating to get
that sort of error with 30K of complex XSL.
