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,
