Subject: 25.0.50; `display-buffer-alist': ALIST is completely undefined

ALIST is mentioned only here:

 ACTION is a cons cell (FUNCTION . ALIST), where FUNCTION is a
  function or a list of functions.  Each such function should
  accept two arguments: a buffer to display and an alist of the
  same form as ALIST.  See `display-buffer' for details.

"of the same form as ALIST"?  Really?  What form is that?  Where is
*anything* said about the form of ALIST?
