Hi,

It seems that the accessibility page has moved here:
https://wiki.contextgarden.net/Input_and_compilation/Accessibility .
Maybe the last example is suitable?

(It seems to correctly embed the alt text in the pdf; this can be checked
by using the `--nocompression` flag and opening the resulting pdf with a
text editor. Not sure how to have the alt text in the exported html,
though; I'm sure others will be able to advise on that better than I could.)

Best,
Florent
