  abstract=      "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."
