Good day, Contexters

I've been using plain TeX for many years (EmTeX, if anyone can remember
that, and latterly XeTeX), but my motivation for getting acquainted with
ConText, rather late in life, is the need to produce tagged PDFs that will
be accessible to the visually impaired (generally using an audio reader),
and I understand (or at least hope) that ConText can help with that.

I'm only just getting started with the *Not so Short Introduction*, and of
course have many questions which I think/hope I will be able to answer
myself from the documentation:  I've not managed to load pstricks or edmac,
for example, but this must be possible, and some primitives such as
\baselineskip seem to have disappeared, together with the font-call system
I'm used to:

\font\umirtenpointsevenfive =
"MinionPro-Regular:+onum:mapping=tex-text:letterspace=1.6" at 10.75pt


All that will come as I read the instructions, but what I'm most interested
to achieve is tagging that will not only produce the usual column of
bookmarks at the left-hand side but will also allow an audio reader to read
such things as alt-text for illustrations and, crucially, read a heavily
footnoted text in the correct order.  For this I take it that the footnotes
will have to be tagged in a special way, allowing visually impaired readers
either to suppress them as the text is read out, or else to include them at
the point where the cue occurs, then revert back to the main text.  With my
XeTeX-produced PDFs an audio reader will simply read all of the main text
on a page, then the footnotes (the last of which may be split between
pages), and then start again on the next page - clearly annoying and
unacceptable to those who can't see the PDF.

I'd be most grateful to be pointed in the right direction - or is what I've
outlined simply not achievable?

Best wishes
