You can take out alttext but we've discussed the property previously and it isn't only applicable to images. There's value in describing complex mathml equations for users as mathml doesn't...

The description methods would likely be the same as for any other html content that needs describing. The daisy precedent for a math description is prodnote but that doesn't translate...

What's the use case for having described math be applied to images of math, though? It's kind of moving us back in that direction of describing the content instead of...

Ya, but how is "described math" as alt text any different from putting in ascii text math instead of an image? We don't treat the latter specially, so what makes...

We really need to try and figure out this "describedMath" mess. I'm looking at how to apply these for the epub guide, and longDescription mentions it's also for describing math:...

And to pile on the ambiguities, if latex is used as the alternative text, do you say the publication has alternativeText, describedMath, latex, or all three?

Anything new on being able to modify the IDPF docs, @iherman? If not, would it make sense to make the change first through ISO @murata2makoto @avneeshsingh @GeorgeKerscher? It's become kind...
