R52 / M:Mc-1

Client Domain has requirements satisfied by zero, one or many Service Domain

Service Domain satisfies requirements of one or many Client Domain

---

Formalization

Bridge.Client domain -> Client domain.Domain
Bridge.Service domain -> Service domain.Domain

Service domain {R52c}

Service domain != Client domain

A Service Domain cannot serve itself. If a Domain 'A' requires the services of itself it already has access to its own internal components. Furthermore, those components are at the same level of abstraction, since they are the same. So there is no need for an External Entity to map to another abstraction layer.
