PDF/UA-1 rule 7.2-21: Natural language for text in ActualText attribute cannot be determined

May be fixed when the cause is a missing document language structure, lang

What veraPDF reports

Natural language for text in ActualText attribute cannot be determined

veraPDF rule 7.2-21 = ISO 14289-1:2014 clause 7.2, test 21, checked on PDF object PDStructElem.

What the requirement says

Natural language for text in ActualText attribute shall be determined

Can it be fixed automatically?

May be fixed when the cause is a missing document language. The fix sets the document language (/Lang) when the file declares none, which lets the language of this text be determined. Not measured for this rule — the free check shows whether it disappears for your file.

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.
