Hi, I think it could be useful if the window which owns the _NET_WM_CM_Sn selection has a name (_NET_WM_NAME and/or WM_NAME). Compiz and xcompmgr already do it.
Btw, a name is already required for _NET_SUPPORTING_WM_CHECK window. So it sounds like a good idea to do the same for the _NET_WM_CM_Sn owner window. So I suggest to add the following to "_NET_WM_CM_Sn Manager Selection" section: "The owner window MUST also have the _NET_WM_NAME property set to the name of the composite manager." PS: I've written a patch for xcompmgr to retrieve the name of the current composite manager if there's already one running.
