+  * There are currently two allowable permission names for this class:
+  * <ul>
+  * <li><code>enableSubclassImplementation</code> - Allows a subclass to
+  * override the default serialization behavior of objects.</li>
+  * <li><code>enableSubstitution</code> - Allows substitution of one object
+  * for another during serialization or deserialization.</li>
+  * </ul>
