    Interface LocalProjectedOperation

    A format adapter's local-engineering → projected-map operation. The operation is deliberately expressed structurally rather than as IFC types; an IFC adapter may fill it from IfcMapConversion, while LandXML or a scan adapter can state a different operation or leave it absent.
