I wrote down a set of electromagnetic relations in
XHTML+MathML: this is both because I got
tired of looking them up in books all the time and so as to test
MathML functionality. And it isn't great: only (a recent
version of) Mozilla displays
something even *vaguely* accurate (but far from pretty). Opera shows every formula as a pretty
much meaningless sequence of letters and numbers (interestingly
enough, the Maxwell-Gauß
equation is named Maxwell-Gau

[sic] in Opera and becomes
simply D=D

, which is certainly true, but not what was
intended). Konqueror is
honest about its inabilities and refuses to even try and open the
file. And the big disappointment comes from Amaya which also refuses to
understand the MIME type
`application/xhtml+xml`

and, even if you force it to, isn't
smart enough to avoid (wrongly) displaying the MathML
semantic content annotation.

****Sigh***.* And this is *two and a half years* after
the standardization of version *2.0* of MathML.
Hullo? Anyone doing any work around here?
