adapt auctex to the latex3 syntax

hello all

I would like to see a latex3 macro name such as \c_something:Nn
"correctly" recognised as a macro name (to obtain the same face as with 
\something)
I've tried to modify the syntax table with

(defun latex-syntaxe-latex3()
   "modifie la table de syntaxe pour faire de _ et : des lettres"
   (interactive)
   (modify-syntax-entry ?_ "w" LaTeX-mode-syntax-table)
   ;; to be completed for :
)

and that works *partially* i.e. I obtain the good face for "\c_" but it 
stops there and the color is not the same for the remaining part of the 
macro name.

What do I miss?

many thanks for any hint

GNU Emacs 23.3.1 on Ubuntu 12.04 / AucTeX 11.86

! Wishfull seeing! It does *not* work at all. The color does not change.

I'm missing more than I thought.

Any help greatly appreciated.

In fact the fontification for commands does not use the syntax table,
but is hardcoded in font-latex.el :

(defun font-latex-match-simple-command (limit)
  "Search for command like \\foo before LIMIT."
  (TeX-re-search-forward-unescaped "\\\\[ <at> A-Za-z]+" limit t))

you can modify this function to :

(defun font-latex-match-simple-command (limit)
  "Search for command like \\foo before LIMIT."
  (TeX-re-search-forward-unescaped "\\\\[ <at> A-Za-z:_]+" limit t))

to get the desired behaviour.

Or perhaps it would be good to have

Maybe having the characters _ and : as words would be too confusing when
editing the actual text (some people also use LaTeX for typesetting
their documents, not just for programming ;)).

Anyway, I guess the straightforward way would be to create a style file
expl3.el ?
