Asynchronous Message (Value)
An asynchronous message (value) is a visual synonym of a message. It adds no additional semantics; it is simply an example of the asynchronous message adapted for use on a timing diagram. This usage of the asynchronous message has the same form as an asynchronous message used on other interaction diagrams: a solid line with an open arrowhead directed from one lifeline to another (possibly reflexive). It is listed separately because the message ends give it a different appearance from other examples. The point on the execution occurrence where the asynchronous messages end represent event occurrences and are important events in a lifeline. There is a single form of presentation in the three different types of interaction diagrams and the two different presentations of the timing diagram.
