Re: PDF Validator Failures?

PDF/UA-1 Sec. 7.18.5 states:
"Links shall contain an alternate description via their contents key as
described in ISO 32000-1:2008."

I think this spec is ill-defined as we're all finding that a global "all
links must have alt-text" just doesn't meet users' needs well. I hope it can
be fine-tuned in PDF/UA-2.

We use our judgment when checking links for alt-text. As long as the link
itself provides enough descriptive information, Alt-text really isn't needed
and in most cases adds unnecessary verbiage to the stream that's hitting a
screen reader user's ears.

Subject: [WebAIM] PDF Validator Failures?

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.
