/**

 * This class is for Serializable permissions. A SerializablePermission

 * contains a name (also referred to as a "target name") but

 * no actions list; you either have the named permission

 * or you don't.

 *

 * <P>

 * The target name is the name of the Serializable permission (see below).

 *

 * <P>

 * The following table lists the standard {@code SerializablePermission} target names,

 * and for each provides a description of what the permission allows

 * and a discussion of the risks of granting code the permission.

 * <tr>

 *   <th scope="row">enableSubclassImplementation</th>

 *   <td>Subclass implementation of ObjectOutputStream or ObjectInputStream

 * to override the default serialization or deserialization, respectively,

 * of objects</td>

 *   <td>Code can use this to serialize or

 * deserialize classes in a purposefully malfeasant manner. For example,

 * during serialization, malicious code can use this to

 * purposefully store confidential private field data in a way easily accessible

 * to attackers. Or, during deserialization it could, for example, deserialize

 * a class with all its private fields zeroed out.</td>

 * </tr>

 *

 * <tr>

 *   <th scope="row">enableSubstitution</th>

 *   <td>Substitution of one object for another during

 * serialization or deserialization</td>

 *   <td>This is dangerous because malicious code

 * can replace the actual object with one which has incorrect or

 * malignant data.</td>
