[xsl] Verifying large XSL transform output

[Matthew Stoeffler <Matthew.Stoeffler@xxxxxxxxxx>]

I have a question about verifying XSL transform output.  I'm moving somewhat
large XML docs --digital books-- from one format into another (archival)
format, with lots of pulling and pushing.  The source format is,
euphemistically speaking, 'interesting', and not the kind of thing you'd
necessarily want to emulate: lots of too-loose content models granting
multiple structural variations for the same intellectual object; much
cross-document referencing via PIs, etc.  The transform scripts are large.  I
know my results are valid in the new format; I'm now trying to confirm that
I'm capturing all the content.  I've done analysis of ID's from source to
output.  I have contemplated ways of counting text nodes, or text string
length, as another possible approach.  I'd love some feedback from the list on
metrics others have tried and what seems to work best.  Thanks in advance.
