The Recursive Layering indicates a direct or indirect recursive layering.
For example, in a routine call layer diagram this shows a recursive call. |

Put any recursive layering below normal layering connections.
This makes the layout clearer because element B depends on A, therefore the connection from A to B should be above the recursive connection of B. If you think of it as a routine call layering, you see that the recursive call of B can only happen after routine A has called B. |
