In designing a binding access model for an application, consider also whether it may be appropriate to combine some of the models previously discussed. In the print service application, it may be desirable for servers to also offer a management interface to specific servers rather than to specific objects; for example, lpr, lpq, and lprm are generic application clients, so it is appropriate for them to bind to printer objects, but if lpr_mgmt is supposed to manage characteristics of a whole service, then it should bind to servers.
