The meaning of module composition
This page explains what it means to import a module and rely on the interface operations implemented by the module. In particular, how one can, at least in principle, construct a single flat Event-B machine from a specification where a final refinement step and its abstraction rely on modules. This serves two purposes: it gives exact characterisation of the behaviour of a modular specification; it serves as a reference for implementation-stage composition strategies.
