 * <P>RelationSupport class conforms to the design patterns of standard MBean. So
 * the user can decide to instantiate a RelationSupport object himself as
 * a MBean (as it follows the MBean design patterns), to register it in the
 * MBean Server, and then to add it in the Relation Service.
 * <P>The user can also, when creating his own MBean relation class, have it
 * extending RelationSupport, to retrieve the implementations of required
 * interfaces (see below).
 * <P>It is also possible to have in a user relation MBean class a member
 * being a RelationSupport object, and to implement the required interfaces by
 * delegating all to this member.
 * <P> RelationSupport implements the Relation interface (to be handled by the
 * Relation Service).
