Hi Rik, I guess it's not supported yet. In "lpdf-fmt.lua" it says: [..] ["pdf/a-3a"] = { -- untested; NEW: any type of attachment is allowed [..] I remember adding the "a-2a" and "a-3a" versions back when Hans and I added experimental support for "PDF/UA-1" (which is based on "PDF/A-3a", but much more limited). This all lies back a few years, can't remember the details. So we have only basic support for "PDF/A-3a", the more advanced features of that format are not supported yet. The main problem here is the lacking PDF/A documentation (ISO pay wall). I guess there is currently no real reason to use that format at all (?).

pdf-online https://www.pdf-online.com/osa/validate.aspxreports:
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?
