TreePath on Diagram class?

Why do you have TreePath property on the Diagram class?
My diagrams have nothing to do with trees, how is that affect me?

Thank you,

One can create tree structures without using a TreeModel. Some operations work on trees, not just the individual selected node(s). I don’t know your application, so I don’t know if this property should have any affect on your application. I would guess not.
