The specification says:
Pin rectangles may be notated as small rectangles that are attached to the symbol for the Action that owns them.
There is one other option to show pins:
The situation in which the OutputPin of one Action is connected to the InputPin of the same name in another Action via an ObjectFlow may be shown by the optional notations of Figure 16.6.
This Figure shows a rectangle in the middle between two actions.
In many diagrams the Pins are shown overlapping the border of their owning Action. According to the specification this is wrong. I suggest to correct following Figures:
- 15.64 (here additionally the frame should be dashed and the keyword «structured» is missing)
