PDF/UA-1 rule 7.18.4-1: A Widget annotation is an Artifact or is nested within … tag instead of Form

Not fixed automatically annotation

What veraPDF reports

A Widget annotation is an Artifact or is nested within %1 tag (standard type = %2) instead of Form

veraPDF rule 7.18.4-1 = ISO 14289-1:2014 clause 7.18.4, test 1, checked on PDF object PDWidgetAnnot.

In Adobe Acrobat’s Accessibility Checker the closest item is “Tagged form fields”.

What the requirement says

A Widget annotation shall be nested within a Form tag per ISO 32000-1:2008, 14.8.4.5, Table 340

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

Links, comments and form fields must be in the tag tree (Link, Annot, Form tags). Export as tagged PDF from the authoring tool, or let a PDF editor tag the annotations, then check the result.
