This does not happen at deployment. The XML fragment in the aspect declaration
in jboss-aop.xml is stored for later use when then aspect is actually
created/instantiated. It is just a matter of writing a new AspectFactory
implementation and plugging it in.

This @Dependency annotation only tells the MC about the dependency. The MC
doesn't know how/where this dependency should be injected. The @SecurityDomain
is on the bean class and it is the aspect that needs this information to lookup
and set the dependency within the aspect. A distinct, non-GenericBeanFactory
implementation of an AspectFactory would be needed here. It would work the
same way the Security aspect works now in the current impl except that they MC
would be able to hold up bean creation because the SecurityDomain dependency
would be published to it via the @Dependency annotation.
