--------------------------------------------------------------

1. Use the same list of behavioural criteria as CDI-74 (which was created to cover interception)

2. Describe correct behaviour on self-invocation - and what is the effect of using proxies

> When implementing interception using proxying the behaour of self invocation is quite well defined, if a method is invoked on the proxy it is intercepted, if it is invoked on the actual bean (usually through self-invocation) it is not.
> When implementing interception though sub classing this is much less well definied, and the only way to track if an invocation is intercepted or not is through a thread local flag. At the moment in weld this is reset when a call is made on a client proxy, so if we have an intercepted bean A and a SessionScoped bean B and A invokes B when invokes A the second call to A is intercepted. If however B is pseudo scoped, then the second invocation is not intercepted. The correct behaviour here should be specified by the specification.
