Hello all and personally Nick, I want to draw your attention to the
following problem. There is only limited possible
transformation between CAdES-X Type 1 signature and CAdES-X Long Type 1
signature. Notably, one must store certificate and revocation values for
signature-timestamp validation in the timestamp itself, hence, after receiving
CAdES-C-timestamp one cannot add or remove these values from
signature-timestamp. An obvious solution is to allow to include
timestamp validation data in certificate-values and revocation-values
attributes of the signature itself. What do you think? Pavel
