[jboss-as7-dev] Integration of managed components (projects)

I need some clarification on this one: http://community.jboss.org/wiki/DomainRequirements It says: "31. Projects must have an internal management API, and not be directly dependent on JMX for their management API. 32. Projects must maintain a management API wrapper over their internal management API. This is an integration requirement." - What does management API wrapper mean in this case? - What's the association between the domain and a managed component? - How do they interface each other (i.e. notification of state changes)?
