There are two flavors of MathML -- presentation MathML represents
expressions in terms of display operators (e.g. subscript and
superscript) while content MathML is a "mathematical" representation
(e.g. index and exponent). Content MathML is pretty much like a
reexpression of Maxima's internal representation (op + args) in XML.
It is annoying that MathML is based on XML instead of Lisp, since
XML is pretty starkly inferior in many ways, but after complaining
about XML for some years, I got on the bandwagon -- if you can't
beat 'em, join 'em.
