Application Framework

      This is where you describe the software classes and interconnections that allow you to handle the System Events in the manner described above. Again, following good writing style, introduce the material before going into details.

Common Pitfall: If your Sequence- / Collaboration- diagrams in Section 4.3 send messages between two objects, then there will probably be some relation between the two objects here. Otherwise you must answer this question: 'how does object A know which object B to send the message to?' It might help to think of it in terms of software references or pointers.
