Note that even though Aster is used to render LaTeX, T.V. Raman's 
dissertation makes it clear that his system does an enormous amount of 
work to recognize the logical structure of the formulas it reads.

If I understand T.V.Raman correctly, for text / audio rendering, 
MathML-Content should therefore be a much better-quality input than 
MathML-Presentation, and I suspect that MathML-Presentation text/audio 
rendering should really be done as a two-phase process that first does 
MathML-Presentation to MathML-Content recognition.
