Not quite ready yet. When the hidden method is used, it passes the

Hi Rik,
as for 6.8-1, did you set MIME type of the attached file (such as in
"type={application/pdf}")?
Oddly, the bookmarks do not appear either way under MkIV, and they do
not appear when the attachment is visible under LMTX. The bookmarks do
appear with a hidden attachment under LMTX.
As far as I understand, only LMTX will receive regular updates now. (But
Hans knows better š
.)
I get both visible attachments and bookmarks in LMTX (latest and
previous latest [ālatestā is the new beta]).
Could you provide a minimal sample that shows the issue?

Hello Pablo (and everyone else),
Here is my test file. You can use "context --mode=hidden file.tex" to
hide the pushpin, orĀ leave out the mode to expose it.
%% Test file for pdf3a compliance.
%%
%% So far, this fails when the attachment is included. Other than the
%% handling of attachments, ConTeXt does a good job with the various
%% PDF/A variants.
%%
%% Testing done locally with the VeraPDF validator (most recently with
%% version 1.14.8) and online with the 3-Heights validator found at
%% https://www.pdf-online.com/osa/validate.aspx (current 2020-01-20).
%%
%% This is not a minimal example.

I have tested with LMTX 2020.02.11 16:41.
*Mime type*
* You can see that the mime type is set in the ConTeXt file and it
appears in the resulting pdf, although not knowing enough about the
pdf file structure I do not know if it appears correctly.
*Validation*
* With the pin hidden, VeraPDF 1.14.8 complains about two occurrences
of clause 6.8 test 1 failure. With the pin exposed, it complains
about one occurrence of clause 6.8 test 1 failure and one occurrence
of clause 6.3.3 test 1 failure (appearance dictionary).
* With the pin hidden, pdf-online.com declares theĀ valid. With the
pin exposed, pdf-online.com fails it because "[t]he appearance
dictionary doesn't contain an entry." They are aware of the
difference between their report and that of VeraPDF.
*Viewing*
* Acrobat Reader DC shows the pushpin, changes the pointer, and
displays flyover text when appropriate and shows the bookmark for
both variants.
* SumatraPDF shows the pushpin, changes the pointer, and displays
flyover text when appropriate. It does not show the bookmark when
the pushpin is visible, but does show it when it is hidden.
* MuPDF does not show the pushpin, instead leaving empty space, when
it should be visible. It does not show bookmarks or any other
indication that there is an attachment for either variant. (MuPDF
can show bookmarks for some other documents.)
* Firefox 73 does not show the pushpin when it should be visible, but
does change the pointer and show the attachment name as a flyover.
Firefox 73 does show the bookmark for both variants.
* Chrome 80 does not show the pushpin when it should be visible, but
does show the attachment name as a flyover. Chrome 80 does not show
the bookmark for either variant. (Chrome 80 does show bookmarks for
some other PDF document.)
* The three viewers listed here that do not show the pushpin do
reserve the appropriate space Ā Āā changing the symbol to the
Paperclip demonstrates that even though the paperclip is not displayed.
Clearly there are issues with the various viewers. How much ConTeXt can
or should do to manage the differences is not clear to me.
