-Protocol mapping is required to map a protocol-agnostic affordance to
-a protocol-specific operation, as implementations of the same affordance
-will differ between protocols. For example, BLE will address a property
-as a service characteristic, while a property in Zigbee is addressed
-as an attribute in a cluster of an endpoint.

 A protocol mapping object is a JSON object identified by the `sdfProtocolMap`
 keyword. Protocol-specific properties are embedded within this object, organized
-by protocol name, e.g., "ble" or "zigbee". The protocol name MUST be specified
