    Description

      To support Long Term Validation of a signature, we need to add a Valdiation-Dictionary to the document. Inside there is most importantly an OCSP-Response of the signers. (can be multiple).
      As Defined in PAdES 4 the following elements will be added to a document: A DSS (Document Security Store) linked to the VRI(s) of the signature(s)
      At first I will provide an example.
