Not that I am aware of; I think the statement itself is more than a
little bit of hyperbole.

It's a very hard choice to make.  I don't have a good answer, really.
I like XHTML better than HTML 4 -- but there _are_ a small number of
legitimate HTML browsers which will have minor to serious problems
with XHTML.

If it were a case of broken HTML, I would be all for saying, "well,
they're broken, they should upgrade" -- but I don't feel this is the
case here.  The change from HTML to XHTML has that 0.56% incompatibility
problem.

Another example, which -is- accounted for in the XHTML compatibility
guidelines, is that you _can't_ use an embedded style sheet via
<style> and effectively hide it from older browsers, in XHTML.  A
friend and I had this discussion last week -- it relates to the fact
that comments in XML (and thus XHTML) can/should be thrown away
completely, so you can't use XHTML comments to hide your CSS.
