    You can optionally enable additional utterances by using semantics. When

    Semantics is supported for the following interfaces only: ModeController,

    Semantics stateMappings are only supported for one interface of the same
    type on the same device. If a device has multiple RangeControllers only
    one interface may use stateMappings otherwise discovery will fail.
 
    You can support semantics actionMappings on different controllers for the
    same device, however each controller must support different phrases.
    For example, you can support "raise" on a RangeController, and "open"
    on a ModeController, but you can't support "open" on both RangeController
    and ModeController. Semantics stateMappings are only supported for one
    interface on the same device.
