PDF/UA-1 rule 7.9-2: ID key … of the Note tag is non-unique
Not fixed automaticallystructure, note
What veraPDF reports
ID key %1 of the Note tag is non-unique
veraPDF rule 7.9-2 = ISO 14289-1:2014 clause 7.9, test 2, checked on PDF object SENote.
What the requirement says
Each Note tag shall have unique ID key
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
The document needs a correct tag tree (structure). The reliable way is to export from the authoring application with “tagged PDF” / “document structure tags for accessibility” enabled; otherwise the tags are corrected in a PDF editor.
