Actually, I was talking about the XSLT part -- as I mentioned in an
earlier part of the post, FO's are hard.

I am in a positive where it would not be diplomatic to name names, but
go to http://www.w3.org/TR/ and read down the list of REC's, PR's, and
WD's, and then count actual implementations for each one (if you want
to be really tough, count only implementations not sponsored in some
way by the W3C itself).

Again, as I mentioned earlier in this message, FO's are hard, even for
CSS1.  On the other hand, only a tiny handful of browser writers have
to deal with that part of the complexity; the real cost of complexity
is the cost of training, learning, etc., and CSS1 is brain-dead simple
in that respect (it does rely on an understanding of the abstraction
of elements, attributes, and data in a tree, but that's a prerequisite
for working with XML anyway).


All the best,


David
