This is what I have in tabkey2.el in nXhtml (though it might be broken
at the moment):
(defcustom tabkey2-completion-functions
'(
("Emacs default completion" completion-at-point
completion-at-point-functions)
;; Front ends (should take care of the rest, ie temporary things,
;; snippets etc...)
("Company Mode completion" company-complete company-mode)

"List of completion functions.
The first 'active' entry in this list is normally used during the
'Tab completion state' by `tabkey2-complete'. An entry in the
list should have either of this forms
\(TITLE COMPLETION-FUNCTION ACTIVE-FORM RESET-FORM)
TITLE to show in menus etc.
COMPLETION-FUNCTION is the completion function symbol.
The entry is considered active if the symbol COMPLETION-FUNCTION
is bound to a command and
- This function has a key binding at point and ACTIVE-FORM is
equal to nil.
or
- The elisp expression ACTIVE-FORM evaluates to non-nil. If it
is a single symbol then its variable value is used, otherwise
the elisp form is evaled.
RESET-FORM is used to reset the completion function before
calling it.
When choosing with `tabkey2-cycle-completion-functions'
only the currently active entry in this list are shown."
:type '(repeat (list string (choice (command :tag "Currently known command")
(symbol :tag "Command not known yet"))
(choice (const :tag "Active only if it has a
key binding at point" nil)
(sexp :tag "Elisp, if evals to non-nil
then active"))
(sexp :tag "Elisp, reset completion function")))
:group 'tabkey2)
