I still have no idea. However I've found that not using a DeploymentScope
seems to work. I would still like to know how to get a definition and what
are the cases when not having a DeploymentScope will not work. Any idea?

Actually it seems it works even with no aop.xml at all! Cool, that's exactly
what I wanted! :-)

Not tried yet.

Not tried yet.

Apparently not!
