* <p>The constants in this class present a strongly typed enumeration
* of common object roles. A public constructor for this class has been
* purposely omitted and applications should use one of the constants
* from this class. If the constants in this class are not sufficient
* to describe the role of an object, a subclass should be generated
* from this class and it should provide constants in a similar manner.
