Take a look at:
http://maxima.sourceforge.net/wiki/index.php/Maxima%20internals
In summary, Maxima expressions are conses with the car also a cons,
caar being the operator and the rest of the car being flags, and the
cdr of the expression being the arguments. There are some expressions
(notably MRAT) which do not follow that scheme, but I think anything
imported from XML can be represented by the ((op ...) args ...) scheme.
