Description

In some case, changing the type of the Lifeline requires to also update the signature of the associated message.
The specification must be more precise before implementing this feature.

In UML 2.5.1, we found:
The signature of a Message refers to either an Operation or a Signal. The name of the Message must be the same as the
name of the referenced Operation or Signal.
NOTE. Lifelines cannot directly represent Types. However, any Lifeline representing a ConnectableElement with a
Type having an Operation with isStatic = true, can accept Messages with a signature associated with that static Operation.
