    Typed attribute schema for controllable load energy resources.

    CIM alignment (IEC 61970-301):
      SMART_HVAC          → cim:EnergyConsumer / cim:ConformLoad (Heating/Cooling)
      SMART_WATER_HEATER  → cim:EnergyConsumer / cim:ConformLoad (WaterHeating)
      CONTROLLABLE_LOAD   → cim:EnergyConsumer / cim:ConformLoad (generic)

    These resources participate in demand-response and demand-flexibility
    programs, responding to OpenADR, OCPP, SunSpec Modbus, EEBus, or
    Modbus control signals.

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