FWIW, even though content negotiation is supposed to be
the solution, I've given up on it where MathML is
concerned;  it really doesn't have the needed resolution.

On the one hand, IE _will_ handle XHTML if MathPlayer is
installed, but not otherwise.  On the other hand,
Opera handles XHTML perfectly fine, but not MathML.
I'm sure I'll live to regret it, but I've gone with
browser sniffing for the case where the "+xml" means +MathML.
