SubscriptionId

A subscription by the bounded context it belongs to and its name (processor.function, or a built-in's wow.…): names are unique within a context only, so two contexts of one service may each have a subscription of one name, such as their wow.snapshot. It keys the failure ledger's entries (me.ahoo.wow.spi.ledger.FailureLedger), so the contexts of a service that share a store keep their entries apart; and it identifies a subscription to the operator (the parked entries' routes) and in the host's configuration, as its key <context>.<name> (wow.subscriptions.[shop.CartSaga.onOrderCreated]): a context's name has no dot, so the key splits at its first.

Construct one with of; the constructor is internal to Wow.
