You thought the browser would take the LaTeX from the @alt and stuff  
it in the accessible name.

This has the downside that if the user doesn't have the helper, it  
can obliterate a
good @alt that the author provided.

Neil has said that their helper, when it is called, is willing to dig  
a little more to get the LaTeX so that the author can put in both the  
LaTeX for those with the helper and their own reading of the equation  
in some markup in the document.

We discussed another option: the helper returning its reading of the  
math
through the API by which it was called;
and Neil preferred an approach where they use what you are already  
doing so the
AT has a minimum of additional logic to code and he (Design Science)  
doesn't have to
negotiate different APIs with each AT or drag them all to the Linux  
Foundation table
to work out a common API for calling the helper, except the most basic.

> When is description used and what should it point to?

The description is the literate reading of the math, from either  
MathML or from LaTeX,
as generated by the helper called by the AT.  It can be stuffed in  
with a 'hiding'
style, at the foot of the page as a footnote, or .. we didn't get  
that far.

What we didn't talk about is the relationship between this  
description and any other
descriptions.  If the author has already supplied a description of  
the mathematical
expression (mathematically correct term v. 'equation') the helper's  
version should
parallel and not obliterate it.  So I was thinking we should tell the  
helper to add
the ID for its description at the front of the list of IDs that  
appear in the
@describedby attribute, if it already exists.  create one if not  
already existing.

The destination modality is very important in that the text the  
helper generates is
very different if German Math Braille is desired or if German speech  
is desired.
That's for the 'helper' API to communicate from AT to helper in the  
near term,
migrating to the helper using the DCCI information in the future.

But yes, the pattern in the markup is the same; the speech/braille/ 
etc. destination
format is out-of-band w.r.t. the markup.  The markup just has a place  
to put
"the desired text as produced by the AT-helper module".
