Cuando un invitado viola este protocolo, xenstored interrumpir\u00e1 la conexi\u00f3n con ese invitado. Desafortunadamente, esto se hace simplemente eliminando al invitado de la administraci\u00f3n interna de xenstored, resultando en las mismas acciones como si el invitado hubiera sido destruido, incluyendo el env\u00edo de un evento @releaseDomain. Los eventos de @releaseDomain no dicen que el invitado ha sido eliminado.
