| /** |
| * This abstract policy assertion validator validates assertions by their qualified |
| * name. Server and client side validation methods return {@link Fitness} based on |
| * following schema: |
| * |
| * <ul> |
| * <li>{@link Fitness#SUPPORTED} - if the assertion qualified name is in the list of |
| * supported assertion names on the server/client side</li> |
| * <li>{@link Fitness#UNSUPPORTED} - if the assertion qualified name is not in the list of |
| * supported assertion names on the server/client side, however it is in the list of |
| * assertion names supported on the other side</li> |
| * <li>{@link Fitness#UNKNOWN} - if the assertion qualified name is not present in the any of |
| * the lists of supported assertion names</li> |
| * </ul> |
| * |
| * For some domains such validation may be sufficient enough. Other domains may |
| * use functionality of this base class as a first step validation before any attempts |
| * to validate content of the assertion. To do this one needs to override and reuse |
| * the default behavior of {@link #validateClientSide(PolicyAssertion)} and |
| * {@link #validateServerSide(PolicyAssertion)} methods. |
