It is my understanding that from a PDF/UA perspective that all links must have the alternative content set. Ideally authoring tools would just set this on all links. For most text links that are not url this is redundant if the text of the link already describes the link's purpose.

I know, I have the same errors with Tables of Content as well as with contextual links. I don't have a good solution. I can choose to ignore them with my own documents but am curious to know how organizations deal with this.

Not sure if it is a defect in what we've done with PDF/UA, the implementation of PDF/UA by conversion tools, a problem with the accessibility checkers or some other problem.

I also sometimes get the error that in a TOC, the <Link> Tag is looking for unique ID's for each TOC entry. Yikes! Why didn't the conversion tool/tagging tool do this?

Cheers, Karen

Whenever I check PDFs using Commonlook, I always get the following errors about link annotation.

"Parent tag of Link annotation doesn't define the Alt attribute." "Link Annotation doesn't define the Contents attribute."

I can fix this fairly easily. But as long as the link is descriptive text, what practical consequence does this have? The descriptive link seems to read in JAWS and NVDA just fine without ALT on the annotation.
