Dan Allen commented on JBSEAM-1670:
-----------------------------------

Oh, and thanks to the syntax of annotation attribute values, this should not affect existing applications because a single value does not require the brackets. It is fully backward compatible. Ah, in thinking about that, we may need to add logic that handles the case when the UNSPECIFIED scope is used. Like I said, the patch is a good start, but needs to be reviewed.

> Right now, your only option for the scope on the @In annotation is an explicit scope or a hierarchical search of all the scopes. I can imagine that there are times when you want to look in a handful of scopes, but not all of them. For instance, anything within a conversation, but not above. Additionally, by making this a multi-value attribute, the developer can override the order in which the scopes are searched. They are searched in the order specified.
> ScopeType[] scope() default {};	
> This would also eliminate the need for the UNSPECIFIED scope since no scopes would assume a hierarchical search. The logic that would have to change is Component#getValueToInject()
