Hello ConTeXt friends,

I am newly exploring ConTeXt in search of a better way to produce PDF/UA-1
accessible and PDF/A compliant documents programmatically. From my early
experiments, ConTeXt docs appear to fully satisfy the veraPDF validator,
but Adobe Acrobat=E2=80=99s Accessibility Checker has three qualms with
ConTeXt-produced documents:


   1. The document is configured to display the file name rather than the
   title in the top of the window (DisplayDocTitle =3D=3D True is what I th=
ink is
   required). See here <https://www.w3.org/TR/WCAG20-TECHS/PDF18.html>.
   2. "Tagged Annotations" fails, suggesting that the document=E2=80=99s li=
nks are
   not properly tagged. I believe the issue is missing "Link - OBJR=E2=80=
=9D (object
   reference) tags. See here
   <https://amp.levelaccess.net/public/standards/view_best_practice.php?vio=
lation_id=3D807>,
   here <https://www.w3.org/TR/WCAG20-TECHS/PDF11.html>, and here
   <http://verapdf.org>.
   3. "Tab Order" fails, I believe because ConTeXt does not specify that
   the tab order should follow the Document Structure, so Acrobat reads it =
as
   unspecified. See here <https://www.w3.org/TR/WCAG20-TECHS/PDF3.html>.


Is there something I could be doing to correct these issues in my ConTeXt
documents? Or is this a change that would have to be made within
ConTeXt itself? I know that Adobe is not the definitive arbiter of what an
=E2=80=9Caccessible=E2=80=9D PDF looks like, but for many organizations, pa=
ssing the
Acrobat accessibility checker is a prerequisite, so it seems worthwhile to
me to make ConTeXt capable of it.

Many thanks!

Connor Jackson
