Connectivity nodes are points where terminals of AC conducting equipment are connected together with zero impedance.
-If the model is a TSO EQ, the ConnectivityNodes should be grouped under VoltageLevel;
If the model is a Boundary EQ, the ConnectivityNodes should be grouped under Line;
If the model is an assembled one, the ConnectivityNodes can be grouped under either VoltageLevel or Line.
With this approach the Line is also in the Boundary set. Instances of ACLineSegment can be in the Boundary set instance of Line or in another instance of Line. Consequently there can be instances of Line that contain only ConnectivityNodes, but no ACLineSegments.
