title: UML common trigger notation
body: <p>What is the notation for a common trigger in a UML state machine? What about multiple common triggers?</p>
  
  <p>Let's say we have at state-machine with 20 states. 18 of these states have a common trigger, that would transition to State_A. Another common trigger would transition to State_D.</p>
  
  <p>What is the graphic notation notation for this? any example would be appreciated.</p>
  
  <p>Kind regards, Ole</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>Is this a valid notation?</p>
