/**
 * Represents the Delta CRL Indicator Extension.
 *
 * <p>
 * The extension identifies a CRL as being a delta CRL.
 * Delta CRLs contain updates to revocation information previously distributed,
 * rather than all the information that would appear in a complete CRL.
 * The extension contains a CRL number that identifies the CRL, complete for a
 * given scope, that was used as the starting point in the generation of
 * this delta CRL.
 *
 * <p>
 * The extension is defined in Section 5.2.4 of
 * <a href="http://www.ietf.org/rfc/rfc3280.txt">Internet X.509 PKI Certific
ate and Certificate Revocation List (CRL) Profile</a>.
 *
 * <p>
 * Its ASN.1 definition is as follows:
 * <pre>
 *     id-ce-deltaCRLIndicator OBJECT IDENTIFIER ::= { id-ce 27 }
 *
 *     BaseCRLNumber ::= CRLNumber
 *     CRLNumber ::= INTEGER (0..MAX)
 * </pre>
 *
 * @since 1.6
