the function frame-live-p is defined as follows:

DEFUN ("frame-live-p", Fframe_live_p, Sframe_live_p, 1, 1, 0,
       doc: /* Return non-nil if OBJECT is a frame which has not been deleted.
Value is nil if OBJECT is not a live frame.  If object is a live
frame, the return value indicates what sort of output device it is
displayed on.  Value is t for a termcap frame (a character-only
terminal), `x' for an Emacs frame being displayed in an X window.  */)
     Lisp_Object object;
  return ((FRAMEP (object)
           && FRAME_LIVE_P (XFRAME (object)))
          ? Fframep (object)
          : Qnil);

In fact, it can return also other values as the doc-string of framep says:

`x' for an Emacs frame that is really an X window,
`w32' for an Emacs frame that is a window on MS-Windows display,
`mac' for an Emacs frame on a Macintosh display,
`pc' for a direct-write MS-DOS frame.

Should we mention all these values also in frame-live-p or is the reference
to the doc-string of framep enough?
