 * a MBean (as it follows the MBean design patterns), to register it in the

 * <P>The user can also, when creating his own MBean relation class, have it
 * extending RelationSupport, to retrieve the implementations of required

 * <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).
