+                 - <attachedDevices/>: permanently attached devices.
+                   The attachedDevices section is a list of devices names.
+                   Their names correspond to device names defined in "devicePorts" section.
+                 - <defaultOutputDevice/> is the device to be used when no policy rule applies
