Accessibility checkers (such as CommonLook) reject PDFs with visible digital signatures, presumably because they lack an Alt-Text feature like standard images have.

We have new requirements to produce all documents for web postings as being accessible, which means we cannot use digital signatures until they become compliant with accessibility requirements.

Please add Alt-Text capabilities or another means of making digital signatures accessibility-compliant. It would be nice if default Alt-Text could be set as part of the digital signature configuration (e.g., "Signature of John Smith".
