* Abstract class for a revoked certificate in a CRL. This class is for each entry in the
* revokedCertificates, so it deals with the inner SEQUENCE. The ASN.1 definition for this is:
*
*
* revokedCertificates SEQUENCE OF SEQUENCE {
* userCertificate CertificateSerialNumber,
* revocationDate ChoiceOfTime,
* crlEntryExtensions Extensions OPTIONAL
* -- if present, must be v2
* } OPTIONAL
*
* CertificateSerialNumber ::= INTEGER
*
* Extensions ::= SEQUENCE SIZE (1..MAX) OF Extension
*
* Extension ::= SEQUENCE {
* extnId OBJECT IDENTIFIER,
* critical BOOLEAN DEFAULT FALSE,
* extnValue OCTET STRING
* -- contains a DER encoding of a value
* -- of the type registered for use with
* -- the extnId object identifier value
* }
