I'm not recommending this but....

I've seen folks use events to trigger event policies that issue the
commands you need.  The main script can then retrieve the saved
file from the event policy.  It's an odd code path, but until there's
a "compare" or "patch" attribute (or a "render='true'" option)
there's no other viable option.

Stylesheets (currently) need the full xml document and we
don't want to buffer it (size and delay), so we went a
different way.

Thanks,
