    The SimpleCMSBundle mostly relies on RoutingBundle and its set of
    configurable capabilities to meet its requirements. It declares an
    independent ``DynamicRouter`` service, with its own specific ``RouteProvider``,
    ``NestedMatcher``, Enhancers set and other useful services, all of them
    instances of the classes bundled with RoutingBundle.
