This exercise explores two different ways to specify existing UML model elements as pattern template arguments.
Instead of creating a new UML element, you can select existing elements by typing the name of an existing element in the pattern instance on the diagram view. Or you can drag an existing element from the Model Explorer view or the diagram view onto the pattern instance.
Before you begin, you must complete Exercise 5: Binding new elements to pattern instances.
You are ready to reapply the pattern to see the pattern to observe its effects the model elements. Go on to Exercise 7: Reapplying the pattern.
