6  * This class is an abstraction of certificate revocation lists (CRLs) that
7  * have different formats but important common uses. For example, all CRLs
8  * share the functionality of listing revoked certificates, and can be queried
9  * on whether or not they list a given certificate.
10  * <p>
11  * Specialized CRL types can be defined by subclassing off of this abstract
12  * class.
