%X Previously, Martin gave formal conditions under which a
   simple design rule guarantees deadlock\-freedom in a system
   with service (client\-server) architecture. Both conditions
   and design rule may be statically verified. Here, they are
   re\-arranged to define service protocol, service network
   (system), and service network component, which together form
   a model for system abstraction. Adding mutual exclusion of
   service provision and dependency between service connections
   enriches abstraction and is shown to afford
   compositionality. Prioritised alternation of service
   provision further enriches abstraction while retaining
   deadlock\-freedom and denying priority conflict, given
   appropriate new design rules.
