QOSCCM11 — Service configuration

Service configuration :
The QoS4CCM standard doesn't speak about access of QoS Enabler at container
level. The 'install_service_reference' operation definition allos to
register service reference at container level but doesn't allow the
configuration of the services in a standard way. This would be useful to
have a configuration interface and to invoke it at service installation.

We propose to define a standard QoS Usage's interface to make service
configuration and to improve 'install_service_reference' operation
definition.
