No unconditional default transitions

Description

Select the diagnostic action to take when a chart does not have an unconditional default transition to a state.

This chart construct can cause inconsistency errors. To locate this construct in your model and correct it, use this diagnostic. If a chart contains local event broadcasts or implicit events, detection of a state inconsistency might not be possible until run time.
