Issue

Functional naming implies that there are no two logical node references (LNode) of the same LN class at any level within the Substation section. This was one of the reasons for introducing the Function/SubFunction elements.
However, these are not available for ConductingEquipment (nor for GeneralEquipment). This makes it impossible, for instance, to model redundant controlers (e.g., CSWI).
(Topic discussed during the WG10 meeting in Berlin.)

Proposal

Add a Function to tConductingEquipment ant tGeneralEquipment similar to Bay, VoltageLevel or Substation. However, the Function of a ConductingEquipment (or GeneralEquipment) shall differ from the Bay/Function in that it shall not allow to include other ConductingEquipments in order to avoid nested ConductingEquipments (or ConductingEquipments in GeneralEquipments).
