What does this mean?

The key <<AA>> is prohibited for PDF/A-1b

6.6.2 - ISO 19005-1 PDF/A Specification:

A Widget annotation dictionary or Field dictionary shall not include an AA entry for an additional-actions dictionary. The document catalog dictionary shall not include an AA entry for an additional-actions dictionary.

NOTE: These additional-actions dictionaries define arbitrary JavaScript actions. The explicit prohibition of the AA entry has the implicit effect of disallowing JavaScript actions that can create external dependencies and complicate preservation efforts.
