* This class models permissions related to serialization. As a subclass

|
|

|
|
* <p>
|
|
* 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><code>enableSubstitution</code> - Allows substitution of one object
|
|
* for another during serialization or deserialization.
