Re: Pdf heading levels

While the HHS checklist does not mention PDF/UA, you are allowed to use it,
as long as you create the structure correctly. Incorrect structures would
be a violation of 3.1 and 3.2. Skipping over headings would be a violation
of 3.4. The PDF checklist does not mention PDF/UA to basically to prevent
confusion, but that does not prevent use.

Note: questions like this usually get routed to me officially. This should
not be seen as an official answer, you can point to it if you reach out to
