I don't know the answers to all these questions. Can you come to the next 
phone meeting so we can discuss them?

Rich will have to say why he wanted to leave it open-ended. I guess I'm 
with you -- I'd rather have it up front.

My example probably had incorrect syntax -- I don't personally even know 
the difference between TeX and LaTeX, which is why I'm trying to ping Neil 
Soiffer here for feedback as well.

But how do you implement it? Should the UA autodetect whether it's TeX or 
LaTeX or something else? How are authors supposed to know what to write? 
How do we achieve interoperability? What's the advantage of leaving it 
open-ended?

The current definition doesn't seem to handle:

    <object role="math" data="foo">a^2+b^2=c^2</object>

Also, when would it be better to have the expression in another element 
than as text in the element itself (i.e. when is labelledby needed for 
role=math)?

Finally, I don't know (La)TeX very good, but shouldn't $ or $$ be implied 
around the expression?
