    Typed attribute schema for grid-network infrastructure energy resources.

    CIM alignment (IEC 61970-301):
      DT        → cim:PowerTransformer
      BUS       → cim:BusbarSection
      FEEDER    → cim:Feeder (EquipmentContainer)
      MICROGRID → cim:Substation / custom microgrid container

    Network resources act as topology anchors in the EnergyResource graph;
    they carry metering points and DER resources as subResources.

    Common attributes (make, model, ratedPowerKw, maxExportKw, maxImportKw,
    telemetryProvider, commissioningDate, location) are inherited from
    EnergyResourceCommon/v1.0 via allOf.
