Dear list,
my sample to add attachments to a PDF/A-3 valid document is the following:
\setuptagging[state=start]
\setupbodyfont[30pt]
\setupbackend [format=PDF/A-3a, intent=sRGB IEC61966-2.1, profile={sRGB.icc,default_gray.icc}, level=0]
\setupcolors[pagecolormodel=auto]
\setupinteraction[state=start] \starttext \startTEXpage[offset=1em] an attachment\attachment[file=xml-mkiv.pdf] \stopTEXpage \stoptext
There are five reported errors when tested with the latest development version of veraPDF (http://downloads.verapdf.org/dev/verapdf-installer.zip ):
- Annotation should have /F value ( https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-and... ); unless their Rect key value 1 equal to value 3 and value 2 equal to value 4, or the annotation subtype is /Popup or /Link.
- Although not reported, the /F value should conform these considerations:
If present, the F key's Print flag bit shall be set to 1 and its Hidden, Invisible, ToggleNoView, and NoView flag bits shall be set to 0.

- Annotations need an appearance dictionary ( https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-and... ); unless the same exception for the /F value apply.
- The /EmbeddedFile dictionary should specify the MIME type in its /Subtype entry ( https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-and... ).
- The /AFRelationship key is missing from the /Filespec dictionary ( https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-and... ). Possible values are: Source, Data, Alternative, Supplement, EncryptedPayload, FormData, Schema or Unspecified (from https://www.pdfa.org/wp-content/uploads/2018/10/PDF20_AN002-AF.pdf).
- The /Filespec lacks association with the PDF document or any of its parts, such as pages ( https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-and... ).
From https://www.pdfa.org/wp-content/uploads/2018/10/PDF20_AN002-AF.pdf, it seems that either the /Catalog or a /Page dictionary (there are other ones, but I would limit attachments in ConTeXt to those two [if not to the /Catalog itself only]) should contain an /AF entry with the reference to the /Filespec object(s). I assume that the value type for the /AF entry is an array of one or multiple object references.
These are all the issues veraPDF finds when validating the PDF document generated from the source above.
I hope it helps. Many thanks for your help,
