DVS checks the full certification path from the certificate's issuer to a trusted point.

Again, the DVCS MAY be able to rely on external information (CRL, OCSP, DVCS).

The current specification defines 4 types of validation and certification services: - Certification of Possession of Data (cpd), - Certification of Claim of Possession of Data (ccpd), - Validation of Digitally Signed Document (vsd), and - Validation of Public Key Certificates (vpkc).

That documentation contains more detailed, developer-targeted descriptions, with conceptual overviews, definitions of terms, workarounds, and working code examples.

4 2.4 Validation of Public Key Certificates ...................... Data Certification Server Usage and Scenarii ................. Functional Requirements for DVCS .............................

The Validation of Public Key Certificates service is used to verify and assert the validity (according to [RFC2459]) of one or more public key certificates at the specified time.
