Thanks, Pablo (and everybody else reading this), [...] \enabletrackers[math.textblobs] [...] will put all math into what I think Hans calls “serialized math" into a footnote (please correct me if I'm wrong). Are there other ways to access that serialized math?
Matthias, no idea, I only found `math.textblobs` included in `math-ini.mkxl`.
One approach to making math and images accessible would be to use modes to replace all figures with their alt-texts and all math with their serialized math, so that the output of ConTeXt would be a PDF where all elements that are difficult to navigate are replaced with plain text. This is, of course, only one of many possible approaches. This would circumvent all tagging issues for the time being.
Not sure whether I understand your approach (after all, math is all Greek to me) and also wondering whether UA-2 could be more useful to use. That being said, I think alternative texts should be used when just tagging text (or formulas) is not an option. Pablo
