As James explains, this is a general problem, i.e. not limited to nxml-mode.

As such, it should be solved generally, rather than hotch-potch fixes in
individual packages.

Usually, I just use ESC TAB for completion when M-TAB doesn't work, and
I guess other users do the same, as I don't hear many complaints that
M-TAB doesn't work...

I don't know what other good alternative there is for M-TAB, but
although C-return could seem ok, I still think it would be better
used for rectangle marking due to the analogy with C-SPC.

Yes, and I make the mistake myself too often!
