David, I agree the page label feature is the appropriate place for non-ordinal or non-contiguous page numbers – so PDF 17 is the way to go for that.  The issue is that stating headings and footers should be artifacts is not so simple.  For example, some footers contain links – links can never be artifacts.  So you are forced to tag them or remove the link.  Many people who are remediating PDFs also don’t have access to change the document so we run into situations where those remediating may not be able to change the section names of the document.

I have compared what PDF/UA with WCAG say about headers and footers and have written up a small report and recommendations on how I think we should proceed with Headers and Footers in PDF documents.

http://davidmacd.com/blog/pdf-headers-footers.html

I think PDF14 requires an update quickly. I could take an action item to propose the rewrite.



Cheers,

David, there are some good but very specific reasons to not artifact header and footer information.  Otherwise running headers and footer should be made pagination artifacts and the Page Labels feature should be used to add Page numbering including section information to identify pages and sections to assistive technology.  The page label feature is pretty powerful and allows flexibility for different number schemes such as Roman numbers and custom label prefixes.

Some instances of header and footer information that might be useful include classification information on classified documents, copyright information, form numbers, or other content that is not located elsewhere in the document.  In general I recommend marking that content as non-artifact content on the first and last page so it does not break up the reading order of content.

Best Regards,

Jonathan

We have a technique for Creating PDF headers and footers, usually inserted
using the source program such as MS Word Headers and Footers. See PDF14.
http://www.w3.org/TR/WCAG20-TECHS/PDF14.html

This causes the screen reader to announce these Headers and footers at the
top and bottom of every page. Sometimes the interrupt reading halfway
through a sentence that continues on the following page. I can imagine this
is quite annoying for screen reader users tp have to listen through a header and a footer between every page.

Visually we just skip over it... Usually most of the information found in the header and footer is available on the home page of the document or some other prominent place.

What is useful is page numbers. However, if the author syncs the page
numbering of the PDF with the document large numbers using PDF17, it makes
me wonder if we should advise the author to mark headers and footers as
artifacts instead...

An organization that teaches PDF, which is fairly well known, and has done
work for Adobe teaches to turn these headers and footers into artifacts so
they will be ignored by a screen reader.

I propose we place a note on PDF14 saying something like this:

 "If the page numbering has been synchronized as in PDF17 and other header
and footer information is available in a prominent place in the document
such as a heading or home page, then headers and footers are not necessary
and can be marked up as artifacts..."
