According to the spec, these are some of the places where Associated Files
(/AF) may appear in 2.x:
{noformat}
• the PDF document catalog dictionary (14.13.3, "Associated files linked to the
PDF document’s
catalog")
• a page dictionary (14.13.4, "Associated files linked to a page dictionary")
• a graphics object (using a marked-content property list dictionary, 14.13.5,
"Associated files
linked to graphics objects")
• a structure element dictionary (14.13.6, "Associated files linked to
structure elements")
• an XObject dictionary (14.13.7, "Associated files linked to XObjects")
• a DParts dictionary (14.13.8, "Associated files linked to DParts")
• an annotation dictionary (14.13.9, "Associated files linked to an annotation
dictionary")
• a metadata stream dictionary (14.3.2, "Metadata streams")
{noformat}
Oh, I had forgotten about this:
https://www.pdfa.org/wp-content/uploads/2018/10/PDF20_AN002-AF.pdf
This suggests that /AF can appear anywhere ... not just in the above in PDF 2.0.
