Thanks Ulrike, This is helpful (and sad) information.
Would it be possible to have ConTeXt produce two documents, one that shows the typeset formula as usual, and a second one that shows instead of the formula the text that Mikael’s example shows as a note? Then screen-reading the second output should be acceptable, at least as far as math is concerned?
