* Domain Model (Entities, value objects, aggregates) depends on "nothing" (PHP, possibly libraries such as Euro)
* Domain Services are defined as interfaces that can only depend, and always depend, on domain concepts (and the domain model)
* Repositories (a kind of Domain Service?) are defined as interfaces that can only depend, and always depend, on domain concepts (and the domain model)
* Implementations of Repositories and Domain Services can depend on whatever (ie Doctrine, Monolog)
* Use Cases can only depend on the Domain Model, Domain Service (interfaces) and Repositories (interfaces)
* Use Cases form the API to the Domain. Higher level code cannot directly access the domain / domain concepts should not occur "outside" UCs.
* Everything bound to the Domain is part of the Bounded Context, nothing else is
* If there are multiple Domains (or rather, Sub Domains), there are multiple Bounded Contexts
* There are no dependencies between Bounded Contexts
* (Applications can use one or more Bounded Contexts, w
