Example: :x1 :a :x2 . :x2 :b :x3 . :x3 :c :x4 . :x4 :a :x3 . :x3 :b :x5 . :x5 :c :x6 . Path :x1 (:a/:b/:c)+ ?Z which goes :x1 -> :x4 -> :x6 i.e. goes through :x2 twice (in some sense) for different reasons. If you link about it in the graph derived by taking :a/:b/:c links: :x1 ":a/:b/:c" :x4 . :x4 ":a/:b/:c" :x6 . it makes sense and has no repeated node. Andy
