Small EWMH inconsistency

[Matthias Clasen]

While reading the 1.4 draft, I noticed that it says:

Note that the actions listed here are those that the Window Manager will
honor for this window. The operations must still be requested through
the normal mechanisms outlined in this specification. For example,
_NET_WM_ACTION_CLOSE does not mean that clients can send a
WM_DELETE_WINDOW message to this window; it means that clients can use a
_NET_CLOSE_WINDOW message to ask the Window Manager to do so.


and a few lines below that, it says:


_NET_WM_ACTION_CLOSE indicates that the window may be closed (i.e. a
WM_DELETE_WINDOW message may be sent). 


What gives ? 
Are applications supposed to send WM_DELETE_WINDOW or
_NET_CLOSE_WINDOW ?
