Very Nice! - By far the best MathML result I have seen so far!
But maybe it's a bit shocking though that the MathML result
is nearly twice the size of the pdf file. :( Well, I guess
I knew that MathML was verbose ...

I think that's a macro in axiom.sty?

These fragments are the 'noweb' source code markups that are
normally handled by the 'noweave' preprocessing which produces
pure LaTeX output. Editing this by hand is ok for this test but
noweave will also generate some extra LaTeX coding that will be
inserted before processing by 'latex'.

This was a bug and patch to tex4ht, right?
When you have time, could you also look at the result of
processing the 'tex' from the following page:
http://wiki.axiom-developer.org/axiom--test--1/src/algebra/fspace.spad
(right-click, save-as on the 'tex' link). This is the example
where I found many occurrences of </msub>...<msub> with improper
start and end tags. Does that also happen to you?

Ah I see, like this ${{}^{HANB} ... $

What does this code do? (Do I need to know? :) It looks very
contrived as a synonym for {}.

Well, please define "wrong way" - latex and dvipdfm swallowed all
that with out a complaint. I will agree that the contents of the
file is a little crufty, but certainly no worse that a code of LaTeX
coding I have seen.
Besides a stronger discipline, how can we insure that our LaTeX
coding meets certain minimum standards so that it doesn't cause
the conversion programs to barf? Do you know of any sort of 'lint'
program for LaTeX that could detect and warn about the "wrong way"
of doing things?
Again, thank you very much for your help.
