+/**
+ * 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 all the possible 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.
+ * <P>
+ *
+ * <table border=1 cellpadding=5 summary="Permission target name, what the permission allows, and associated risks">
+ * <tr>
+ * <th>Permission Target Name</th>
+ * <th>What the Permission Allows</th>
+ * <th>Risks of Allowing this Permission</th>

+ * <tr>
+ *   <td>enableSubclassImplementation</td>
+ *   <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>
+ *   <td>enableSubstitution</td>
+ *   <td>Substitution of one object for another during
+ * serialization or deserialization</td>

+ * malignant data.</td>
