The drag and drop concept could be important in order to track the
state elements
used in more than one diagram.
It is not recommended to use the same element in different diagrams,
but it could be important for DSL modeling to have this option.
In a state diagram, you can drag and drop from the XMI 2.1 Editor the following
element:
State
Select a state element in your XMI 2.1 Editor and drag it to the
Statechart Diagram.
Release the mouse button to drop it into your diagram editor (e.g. State1)
