| * 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://tools.ietf.org/html/rfc5280">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) |
