Hi Antonio

The CDI spec doesn't have an appendix. You must be looking at an old version.

I sent this to Werner in response to his mail. Unfortunately due to the fact I can't post to the EE EG, I doubt you saw it.

> At some point CDI had "deployment types" which were essentially an open set of "project stages". These were simply an annotation, meta-annotated with @DeploymentType.

> CDI 1.0 replaced these with alternatives, which do essentially the same thing as far as CDI is concerned (as you can apply them on stereotypes).
