[xslt] Locating 'Invalid type' errors

[Mark Howe <mark cyberporte com>]

Hi,

I get a lot of these (usually because I have omitted an exsl:node-set()
to allow further processing of an RTF), and they can be a real pain to
locate, because LibXSLT doesn't report a line number, or even a file. I
assume this is because it's a runtime error that is only identified when
the offending data gets to the top of the stack, but I wondered if
anyone had any tips on isolating the problem more easily.

Regards,
