[cdi-dev] explicit bean archives discovery-mode 'annotated'

[Martin Kouba]

Hi Mark,

First of all you're talking about _implicit_ bean archives - explict 
bean archive contains a beans.xml with bean-discovery-mode of all, with 
no version number or an empty file.

With regard to usability (from the extension developer point of view) - 
could you give some practical examples? AFAIK it's really useful from 
the app developer point of view.
