A join is a compound transition that merges
segments originating from states, final activities, or connectors
in different orthogonal components.
IBM® Rational® Rhapsody® automatically
generates a join when you combine source segments. The segments entering
a join connector must not have labels, as shown in the following figure.
Note: If the model contains joins from more than two
concurrent states, this situation generates an error. This situation
is a Rational Rhapsody restriction
in that the error is a violation of MISRA rule 33.
