Schemas and the Agregated PNode

One of the sub-types of the EmixInterface is the Aggregated PNode. The definition of the Aggregated PNode (from the CIM) is

An aggregated pricing node is a specialized type of pricing node used to model items such as System Zone, Default Price Zone, Custom Price Zone, Control Area, Aggregated Generation, Aggregated Particpating Load, Aggregated Non-Participating Load, Trading Hub, DCA Zone

Question:
Should the EMIX definition of an Aggregated PNode be an array of Nodes rather than a single entity?
