Re: Should PDF documents have headers and footers on every page?

>So this issue is very much a user preference and thus flexibility should

Unfortunately, it's not in the user's control to toggle the header/footer
from being an artifact or not. So I think we should provide advice to
authors, because they seldom know the requirements of screen reader users...

If possible I'd rather not contradict the PDF/UA because that just creates
headaches for authors who are under both standards. Unity where possible,
and when it's not possible we should document why authors should do
something different.

Jonathan, you brought up a good point about PDF documents that don't have
source documents but need to be remediated, (e.g., cannot add section
headings).

Anyway, perhaps it's not possible to unify with the PDF/UA on this... I've
tried my best here, I'm open to others opinions...

Cheers,

David MacDonald
