I guess there are a few things in WCAG that do not apply to PDF files,
keyboard focus outline (2.4.7) and maybe text resizing (1.4.4) come to
mind. I'm honestly not sure if there's a way to customize focus
outline or resizing in PDf files (well, assuming the PDF file is real
text, not an image of text of course).
Then there are interaction specific criteria like change of context on
focus or on state change (3.2.1 and 3.2.2) which I'm not sure would
apply to PDFs, fortunately I've managed to stick to the more
traditional and static ones, not testing the limit of what's
technically possible in the PDF format.

With forms, I don't know if there is a PDF equivalent of
aria-describedby to assign a tag as the accessible description for
another focusable tag (e.g. error message or tooltip scenarios).
