Hello list,
The following document fails PDF/A-3a validation. It passes without the
attachment.
\setuplanguage [en]
\setuptagging [state=start]
\setupinteraction [state=start]
\setupbackend [format={pdf/a-3a},profile={default_gray.icc},
intent={ISO coated v2 300\letterpercent\space
(ECI)}]
\setupstructure [state=start,method=auto]
\setupcolors [pagecolormodel=auto,start=yes,rgb=no,cmyk=no]
\setupbodyfont [Palatino,10pt]
\starttext

pdf-online <https://www.pdf-online.com/osa/validate.aspx>reports:
Validating file "test.pdf" for conformance level pdfa-3a
The key F is required but missing.
The appearance dictionary doesn't contain an entry.
File specification 'testa.pdf' not associated with an object.
The document does not conform to the requested standard.
The document doesn't conform to the PDF reference (missing required
entries, wrong value types, etc.).
The document contains hidden, invisible, non-viewable or
non-printable annotations.
The document contains annotations or form fields with ambigous or
without appropriate appearances.
The document does not conform to the PDF/A-3a standard.
Done.
My understanding is that 3-a should support both pdf and non-pdf
attachments. This fails in a similar manner with both pdf/a-3a-validated
files and with plain text files. I also tested with verapdf, and it also
rejected the document with an attachment.
Is this my error, or is it not yet supported?
