[veraPDF-users] value type for /AF entry

Dear list,

validating a PDF/A-3 document with an attachment, the latest development version of veraPDF complains of missing /AF reference in /Catalog, /Page or similar element.

I found https://www.pdfa.org/wp-content/uploads/2018/10/PDF20_AN002-AF.pdf. But in order to report the issue to the PDF creation tool, I need to know for sure which is the value type and the value of the /AF entry.

I guess it should be an array of one or multiple /EmbeddedFile object references, such as in:

/AF [8 0 R 10 0 R 40 0 R]

Could anyone confirm this?

Many thanks for your help,

Pablo
