Helle,

  PDF files can contain digital signatures. If the PDF file is
properly tagged for accessibility, the digital signature fields will
be accessible via Acrobat's MSAA support. Screen readers will be able
to read the information provided in the PDF file about the signature,
and users will be able to digitally sign PDF files.

  The default digital signature implementation that comes with Acrobat
does have an accessible UI. However, there are also third party
digital signature implementations that can be loaded into Acrobat, and
they provide their own user interface for signing the document. The
third party is responsible for the accessibility of that interface.
  
  The spec for Acrobat's MSAA support for digital signatures, as well as
other pieces of document content, can be found at
