    Canonical base schemas shared by all typed EnergyResource kinds.

    v1.1 change: power fields now use QuantitativeValue {value, unit}:
      ratedPowerKw   → ratedPower   (typical unit: kW)
      maxExportKw    → maxExport    (typical unit: kW)
      maxImportKw    → maxImport    (typical unit: kW)

    Optional administrative attributes added (non-breaking; all optional):
      serialNumber — manufacturer asset serial. CIM: EndDeviceInfo.serialNumber.
      inspection   — commissioning/safety inspection record (date, result,
                     inspectorId). Aligned to IEEE 1547-2018 commissioning
                     evaluations and CEA connectivity inspection.
      aggregator   — third-party demand-flex enrolment block (id, name,
                     controllable, enrolledOn). Aligned to IEEE 2030.5 and
                     IEC 61850-7-420 DER control roles.

    The unit field holds a QUDT unit code that expands to a full IRI in
    the JSON-LD context via qudt:unit (e.g. "kW" →
    http://qudt.org/vocab/unit/KiloW).

    EnergyResourceCommonAttributes — the attributes bag base.
    EnergyResourceCommon — the structural envelope inherited by every kind.
