What is required for a class to be interceptor?
(haven't been in JEE world for a while :-))

Does it need to implement some interface?
Or is proper api enough -- e.g. a plain class which has the right method?
(in JBoss AOP, afair, it was enough to have single param method "invoke" with InvocationContext param)

Just asking on how to easily recognize the interceptors,
since I've just written a single-pass scanning MC lib [1],
where it would be trivial to add recognized interceptors by default to Weld' metadata.
(we already do/add a bunch of default things for things we recognize as Weld in JBossAS/MC)

But I guess we then introduce ordering issue?
