PDF/UA-1 rule 7.18.5-2: A link annotation does not include an alternate description in the Contents key

Not fixed automatically structure, annotation, alt-text

What veraPDF reports

A link annotation does not include an alternate description in the Contents key

veraPDF rule 7.18.5-2 = ISO 14289-1:2014 clause 7.18.5, test 2, checked on PDF object PDLinkAnnot.

What the requirement says

Links shall contain an alternate description via their Contents key as described in ISO 32000-1:2008, 14.9.3

Can it be fixed automatically?

Not fixed automatically. This failure needs the authoring tool or manual remediation; the automatic fix does not change it.

How to fix it by hand

Alternative text is human work: describe each image, formula or link in the authoring application (alt text field) or set it in the PDF editor's tag properties. No automatic tool can write a meaningful description for you.
