> 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|https://en.wikipedia.org/wiki/PAdES] 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.
