Not just tagging (which is nice 'cause it allows the reading order to  
be set and heads &c. to be suppressed), but also a sane encoding for  
all characters.

My first question would be if \usepackage{mathptmx} improves things.  
This should only leave the extensible math elements (braces &c.) in  
the TeX math encodings.

Second, have any concrete plans been made for (La)TeX support of the  
STIX fonts? It's still listed as a ``next task'' at the STIX page on  
the AMS site.

Third, perhaps this would be a good time to snag a copy of  
Microsoft's new ``Cambria'' math font (incl. in the Office 2007 beta)  
and see if it works well? Have the person see if this works any better:


I suspect the best authoring setup would be to use something like  
William Hammond's Gellmu and have two conversion paths, one to LaTeX,  
another to some sort of XML optimized for a screen reader. Or just  
defer reading a .pdf and always use the TeX source?

I made a quick test .pdf and while all the text was read okay, it  
wasn't made understandable:

a two plus b two = c two

is _not_ equivalent to:

$a^2 + b^2 = c^2$
