That is correct, PDFs don't have a long description capability. For this I
would put an one-liner, to see a full description go to {www link/PDF
page}. Then since you can manipulate the reading order very easily, just go
through it lineally by the way of text then code. The two things I would
do differently is the vertical text and the text blurbs that are short, and
mark them up as figures. The reason for vertical text is probably
self-explanatory. The text may not be, I would tag some as figures is to
supply more context. For example "geo"=>nil depreciated. If that variable
is depreciated, why is it in a model? By tagging either the text as a
figure you can add alt text to say the variable is depreciated because
____. PDF tags in general can have alt text, but think it has various
results.
