TElCMSSignaturePolicy class

TElCMSSignaturePolicy stores information about the signature policy of a CMS signature. Signature policy is a set of rules which regulate signature creation and validation. The signature policy is identified by its unique PolicyIdentifier, and PolicyHash value. Signature policy may be qualified by some additional information, which is available via the Qualifiers property.
If the signature policy can be unambiguously determined by verifier, it is not necessary to include its identifier and hash value into the signature. In this case, Implied property must be set to True.
