Completion keys and rectangles

M-TAB is very often used by the window manager. "(emacs) Symbol
Completion" therefore advices to use ESC TAB
or C-M-i instead to avoid that when using a completion command in Emacs.

nxml-mode avoids the problem by binding C-RET as well to
nxml-complete, and only that when Emacs is used under
a window system. (See nxml-bind-meta-tab-to-complete-flag.)

But there is an unfortunate collision in that cua-mode uses C-RET for
cua-set-rectangle-mark, so cua-mode people don't
get any binding at all for nxml-complete.

What do you think is the best solution to the window mangers vs.
completion in emacs problem? Would it be better if
key-description described M-TAB as ESC TAB or C-M-i if there is reason
to think M-TAB won't work? Would it be good to have an
alternative key for M-TAB? Is C-RET OK for that, or should that be
used by rectangle commands?

At least I think nxml-mode shouldn't have its own solution, but behave
like other modes with a corresponding completion
command, however that should be.
