 * A JAX-RS meta-provider for dynamic registration of post-matching providers

 * definitions defined on any registered resource filter or interceptor instance.
 * 
 * Providers implementing this interface MAY be annotated with
 * {@link javax.ws.rs.ext.Provider @Provider} annotation in order to be
 * discovered by JAX-RS runtime when scanning for resources and providers.
 * This provider types is supported only as part of the Server API.
