Hmm, Tomas, this is interesting.  I have thought about using babel for this
sort of thing, but assumed that the textual overhead would be too high to
make it worth it (It'd be ugly, and not that fun to generate).  I don't
suppose you'd be so kind as to past in an example that shows this kind of
thing in action?  Even just an example text itself, with the structure and
some blocks. (And of course, I do still owe you my examples of org+xetex).
