> It is often desirable to output a value from a nested conversation to its parent.
> One possible way is to add a property to the @Out annotation (i.e.: @Out(scope=CONVERSATION, level=PARENT)). If there's no outer conversation it can propagate to SESSION.
> Alternatively, it can be explicited by the inner conversation via the @Begin or @End annotations. (i.e.: @Begin(nested=true, outputs="parameter1,parameter2"). The variables "parameter1" and "parameter2" would be promoted to the outer conversation when the inner one ends. I think @Begin is better since a conversation may end via a pageflow <end-conversation/>. Also, this is similar of how we usually declare methods in any language (output explicit in signature).
