http://www.pragma-pod.com/ -> mathml processing (couple of years old but it 
still runs; not the latest version of context btw)

In the context distribution is a more advance demo but that's too much off 
topic for this list.

In context (roughly):

\setupoutput[pdftex]

\usemodule[mathml]

% \usetypescript[palatino][texnansi] \setupbodyfont[palatino]
% \usetypescript[palatino][texnansi] \setupbodyfont[times]
% \usetypescript[fourier] [ec]       \setupbodyfont[fourier]

\starttext
     \startTEXpage
         \startXMLdata
