Oh, as usual with PDF association…
That’s not how you promote open standards.
(Didn’t check, jost forwarded the message.)
2. Well-Tagged PDF (WTPDF)

well, tagging ...
Of course.
But you asked for wanted accessibility features:
sure.
We have \pdfbackendactualtext{visible}{alternative}, can we get
alternative text (ActualText) for images?
Not automatically, of course (if someone wants AI descriptions they can
implement a module), just as a keyword in \externalfigure?
we can add a description option that then can eb used in the wrapper
(not that it helps much to make an image accessible)
btw, someone showed me what this acrobat liquid mode does to a document
... the fact that one has to apply 'ai' to a document is a bad omen and
makes one wonder ... but anyway, big tech, big money, etc so ... (after
visiting a typesetting museum today one again realizes that a few
decades from now one will look back in a certain way, not all is progress)
one thing we need to keep in mind is that as soon as 'obsolete' and 'not
to be used' enters descriptions (which kind of contradicts the
flexibility of sofware) one can also wonder how older documents can ever
match a standard; i often get the impression that instead of some
thinking ahead we end up adapting to what can't be done or what went
wrong (and calling something a standard can then be a way to obscure)
anyway, one way or the other we will cope (and it depends on user demand
which in turn depends on organizational demand)
