* This interface has to be implemented by any MBean class expected to

* represent a relation managed using the Relation Service.
|

* <P>Simple relations, i.e. having only roles, no properties or methods, can
|
||||
* be created directly by the Relation Service (represented as RelationSupport
|
||||
* objects, internally handled by the Relation Service).
|
||||
* <P>If the user wants to represent more complex relations, involving
|
||||
* properties and/or methods, he has to provide his own class implementing the
|
||||
* Relation interface. This can be achieved either by inheriting from
|
||||
* RelationSupport class, or by implementing the interface (fully or delegation to
|
||||
* a RelationSupport object member).
|
||||
* <P>Specifying such user relation class is to introduce properties and/or
|
||||
* methods. Those have to be exposed for remote management. So this means that
|
||||
* any user relation class must be a MBean class.
