PDF/UA-1 · CLAUSE 7.1
Document is flagged as having unreliable tagging
The Suspects flag is set to true, which is how a producer records that its own tagging may be wrong.
Why it matters
The tagging cannot be trusted, so no conformance claim is possible even if every other check passes.
How to fix it
- Review the tag structure and reading order manually, correcting whatever the producer was unsure about.
- Once verified, clear the Suspects entry in the MarkInfo dictionary.
- Do not clear the flag without reviewing the tags: it exists to signal genuine uncertainty.
