AFAICT, the available XSLT profilers will at best tell you what
templates have been used, not what templates haven't been used.  The
ones that just report which templates have been used won't help you, for
example, to work out which parts of a xsl:choose haven't been exercised.

I know of one work-in-progress to make a XSLT coverage tool, but I don't
when or if that will be cooked enough to be made public.

If you also have your input and output schema, you may get some joy from
the XSLV static validation tool at
