title: Is a state without a direct transition allowed in UML state diagram?
body: <p>Is a state without a direct transition allowed in UML state diagram (SD) like the below drawn with StarUML?</p>
  
  <p>State1 is not directly involved in any transition so I'm in doubt wether this is allowed in UML / desirable. I think in my application I'm actually modeling multiple objects in a single SD.</p>
