UMLR — Page: 492-493

Hello, it is not clear to me whether it is still possible in UML2.0 to specify in interaction diagram (either sequence or communication) broadcast actions and lifeline representing multi-object. Figures Fig.14.22 and 14.23 (Superstructure 05-07-04), actually show the possibility of representing instances of the same type (class B) each one represented by a different lifeline: the selectors in that case are used to identify one specific instance and not a set of instances.
