I'll have to agree with Stefan.

js2, nxml, they are fundamentally different than traditional emacs modes, in
that each have a parser that fully understands the languages at syntax
level.

emacs's syntax coloring is based on text pattern matching. It might work
faster or more smooth right now, but from technology point of view, its one
generation behind.

of the 2 approach, the full parser is also a order more difficult to write.

it'd be nice if emacs provides syntax parsing infrastructure.... nmxl, js2,
cedet, can be leads in this direction and see how things work out.

Including expesso-mode is also very good i think, as it provide tried and
true solution that just works.

my 2 ¢. :)
