[xsl] Getting ant to tell me which xslt processor is used

[Jonathan Robie <jonathan.robie@xxxxxxxxxx>]

I've inherited a tangled web of stylesheets used by people on various 
platforms, and their XSLT processors sometimes give different results 
for the same stylesheets.

I'd like to know which XSLT processor each one is using.

$ ant -v -d   gives lots of information, but beyond telling me TRAX is 
used, it says nothing about which XSLT processor. Is there a way to get 
ant to 'fess up?
