This meta service supports the XAccessController interface for checking
security permissions.
@attention
The specific service implementation of this meta service has to take care
of bootstrapping problems, i.e. recurring calls during initialization
have to be resolved. This happens when the implementation calls other
service implementations.
Also, it obviously has also to be ensured that the object is process-local
to assure that permission checks are not corrupted via insecure inter-process
communication.
