Added the missing case. Validation does not complain now and it should fix #2432

      <validationReport jobEndStatus="normal" profileName="PDF/A-3u validation profile" statement="PDF file is compliant with Validation Profile requirements." isCompliant="true">
        <details passedRules="148" failedRules="0" passedChecks="26513" failedChecks="0"></details>
      </validationReport>

Might be a silly question, but did you also check other places in the code where PDFA* is used for decisions and which should be extended? Maybe there are some, I don't know.

That said, this change certainly cannot do harm and obviously improves PDF/A-3u support.

It is not really that silly because I did not check prior to this PR. I did check now and it seems to the only place it was missing
