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.
