Hi John,

Yes it doesn’t seem to be explicitly written (I’m still looking) but reading at the beginning of chapter 12, it’s implicit that there’s one container that do one bean discovery and fire on set of events for type discovered. So IMO, it's implicit that extensions are not limited to their current archive and have the same « visibility » level than the CDI container : i.e. the current application.
This said, it couldn’t hurt to write it explicitly.
