 * ServiceRegistration is a data object containing information regarding a

 * or controls multiple peer services. In order to do so it needs an internal
 * key used only by the composite service. With this key the composite gets a
 * reference to the peer. In some situations it will be necessary to use a peer
 * with a different name. reserveAs is a method which will re-bind the composite
 * to a differently named peer service.
