+	Many compositors will assign user-friendly names to their outputs, show
+	them to the user, allow the user to refer to an output, etc. The client
+	may wish to know this name as well to offer the user similar behaviors.
+
+	The name is a UTF-8 string with no convention defined for its contents.
+	Each name is unique among all wl_output globals. The name is only
+	guaranteed to be unique for the compositor instance.
+
+	The same output name is used for all clients for a given wl_output
+	global. Thus, the name can be shared across processes to refer to a
+	specific wl_output global.
+
+	The name is not guaranteed to be persistent across sessions, thus cannot
+	be used to reliably identify an output in e.g. configuration files.
+
+	Examples of names include 'HDMI-A-1', 'WL-1', 'X11-1', etc. However, do
+	not assume that the name is a reflection of an underlying DRM connector,
+	X11 connection, etc.
+
+	The name event is sent after binding the output object. This event is
+	only sent once per output object, and the name does not change over the
+	lifetime of the wl_output global.
+
+	Compositors may re-use the same output name if the wl_output global is
+	destroyed and re-created later. Compositors should avoid re-using the
+	same name if possible.
+
+	The name event will be followed by a done event.

+	Many compositors can produce human-readable descriptions of their

+	output selection purposes.
+
+	The description is a UTF-8 string with no convention defined for its
+	contents. The description is not guaranteed to be unique among all
+	wl_output globals. Examples might include 'Foocorp 11" Display' or
+	'Virtual X11 output via :1'.
+
+	The description event is sent after binding the output object and
