Dear All,
When tagging an image, it looks like the provided alternative text is used
verbatim. That means no TeX commands are interpreted, nor any math is being
interpreted. Is it possible to serialize the math in an alternate text (as the
tracker does with the non-ALT math in the example below)?
I can do this manually, but my figures contain quite a bit of math, and it
would be nice if alternate text for math is provided consistently throughout
the document.
Thanks,
Matthias
