Organizing Maven dependencies

With comments to help users to check if some dependency can be removed in their applications.

Questions:

1) Why `javax.inject:javax.inject` is provided but `javax.annotation:javax.annotation-api` isn't? Both are provided by appserver but no by servlet containers. The same for `javax.interceptor:javax.interceptor-api` and `javax.ejb:javax.ejb-api`. The default dependencies should focused in appserver or servlet containers?

2) Why `org.hibernate:hibernate-validator-cdi` is provided? May be this artifact should only test scoped, because we need to use in tests. Or if our focus is on servlet containers should compile.
Removed because is part of Java EE 6.
