Alas, no. We are doing validation of sorts to the documents we are using -
but since we've started a very long time ago (two years :-) it isn't XSLT
based. It isn't even DTD based since we needed an XML way to manipulate the
"language" file, so we used our own very limited XSchema-like XML language.
We were planning to migrate to XSchemas if/when they are ever finalized.

Well, in XSchema you can trivially express complex regular expressions which
would be a real pain to convert to XSLT. Essentially you'd need to simulate
the resulting state machine. On the other hand, it isn't clear you really
need this sort of constraints in real world schemas (at least not often),
and there are other things you can easily express in XSLT which you can't do
in XSchema at all (such as depending on attribute values). It all balances
out - I hope.

Right.

One of the marks of a good standard/theory/piece of code is that you get out
of it more then you put into it :-)
