+  <description summary="Primary selection protocol">
+    This protocol provides the ability to have a primary selection device to
+    match that of the X server. This primary selection is a shortcut to the
+    common clipboard selection, where text just needs to be selected in order
+    to allow copying it elsewhere. The de facto way to perform this action
+    is the middle mouse button, although it is not limited to this one.
+
+    Clients wishing to honor primary selection should create a primary
+    selection source and set it as the selection through
+    wp_primary_selection_device.set_selection whenever the text selection
+    changes. In order to minimize calls in pointer-driven text selection,
+    it should happen only once after the operation finished. Similarly,
+    a NULL source should be set when text is unselected.
+
+    wp_primary_selection_offer objects are first announced through the
+    wp_primary_selection_device.data_offer event. Immediately after this event,
+    the primary data offer will emit wp_primary_selection_offer.offer events
+    to let know of the mime types being offered.
+
+    When the primary selection changes, the client with the keyboard focus
+    will receive wp_primary_selection_device.selection events. Only the client
+    with the keyboard focus will receive such events with a non-NULL
+    wp_primary_selection_offer. Across keyboard focus changes, previously
+    focused clients will receive wp_primary_selection_device.events with a
+    NULL wp_primary_selection_offer.
+
+    In order to request the primary selection data, the client must pass
+    a recent serial pertaining to the press event that is triggering the
+    operation, if the compositor deems the serial valid and recent, the
+    wp_primary_selection_source.send event will happen in the other end
+    to let the transfer begin. The client owning the primary selection
+    should write the requested data, and close the file descriptor
+    immediately.
+
+    If the primary selection owner client disappeared during the transfer,
+    the client reading the data will receive a
+    wp_primary_selection_device.selection event with a NULL
+    wp_primary_selection_offer, the client should take this as a hint
+    to finish the reads related to the no longer existing offer.
+
+    The primary selection owner should be checking for errors during
+    writes, merely cancelling the ongoing transfer if any happened.
