Hi Bill!

This pops up quite often.
Actually the spec is pretty much silent on this and defines nothing else than 
CDI being based on JSR-330. But the TCK defines that any JSR-299 container also 
must fully pass the JSR-330 TCK as part of the compatibility check. 

Means CDI containers need to support it, but it is not really defined how it 
should behave.
In OWB we just treat it as alias for @ApplicationScoped. I'm not 100% sure if 
it's the same for Weld, but I think to remember discussing about it with either 
Jozef or Pete that they do it effectively the same way. Needs ack from them 
though.

My personal suggestion is to avoid it. 

There is a slightly broader issue hidden in this topic actually.
As per explanation above, each CDI container must also support scopes annotated 
with @Scope (from atinject, not @NormalScope from CDI). But atinject does 
nowhere define how to register Contexts for those scopes. In CDI we should do 
pickup contexts for those scopes but it's probably not well tested nor defined 
how those contexts should behave. 
I'd personally would expect them to just get injected without the Contextual 
Reference proxies but as direct Contextual Instances and otherwise be pretty 
much the same like standard CDI scopes. But that needs ack + wordig by my 
fellow CDI EG members.
