Jonathan comment:
>For example, some footers contain links – links can never be artifacts.

David Response:
I put a link in a MS Word footer, and exported it. It appears to be marked
as an artifact, even though it can receive tab focus.
I have a screen shot at the bottom of the discussion article here:
http://davidmacd.com/blog/pdf-headers-footers.html

Perhaps information can be added in meta data or added to the tag tree in
acrobat when the original is not available. This would allow us to
cordinate with 7.8 of PDF/UA


Cheers,

David MacDonald
