+description: >
+    Implement to emit D-Bus signal for PLDM Event Messages. PLDM Event
+    Messages are PLDM monitoring and control messages that are used by
+    a PLDM terminus to synchronously or asynchronously report PLDM events
+    to a central party called the PLDM Event Receiver.
+
+    When the PLDM daemon receives a sensorEvent of type stateSensorState,
+    it emits the StateSensorEvent signal.
+
+    This signal would be used by PLDM Requester apps on the BMC, which
+    will rely on this signal to determine state changes on a connected
+    PLDM entity.
+
+    More information about PLDM Event Messages can be found at DSP0248
+    version 1.2.0 section 13.
