| 38 | * <p> |
| 39 | * The extension identifies a CRL as being a delta CRL. |
| 40 | * Delta CRLs contain updates to revocation information previously distributed, |
| 41 | * rather than all the information that would appear in a complete CRL. |
| 42 | * The extension contains a CRL number that identifies the CRL, complete for a |
| 43 | * given scope, that was used as the starting point in the generation of |
| 44 | * this delta CRL. |
| 45 | * |
| 46 | * <p> |

| 48 | * <a href="http://www.ietf.org/rfc/rfc3280.txt">Internet X.509 PKI Certific |
| 49 | ate and Certificate Revocation List (CRL) Profile</a>. |
