        public static final java.lang.String DEFAULT
        The default scope is a singleton within the Registry. A single instance will be created on demand. The lifespan of the instance lasts until the registry is shut down. Some implementations will want to know when the Registry is shutdown; they should register for notifications via the RegistryShutdownHub service.

        public static final java.lang.String PERTHREAD
        An alternate scope provided with Tapestry; a per-thread instance is created on demand, behind a shared proxy. Method invocations on the shared proxy are forwarded to the per-thread instance. Each per-thread instance lasts until the thread is cleaned up (at the end of a request for a web application). Some implementations will want to be notified before being discarded and should register with the PerthreadManager to receive notifications.
