Umm, did you mean hypothetical? 

I was understanding (guessing?) that you didn't have to handle the
generalized case... In the general case, yes, that's a pain: we're up
against the same thing though I think we're going to be able to
restrict/control the fragments and don't have to handle everything.
Having a XSLT processor that supports eval() will likely suffice for us,
though truthfully I haven't spent a whole lot of time thinking about
this yet.

You mean as an option for like the entire universe? Ok, I think I'd vote
for that as well ;-)
