-Status Text: This is a living document. Readers need to be aware that this specification may include unimplemented features, and details that may change. <a href="https://w3c.github.io/ServiceWorker/v1/">Service Workers 1</a> is a version that is advancing toward a W3C Recommendation.
 Abstract: The core of this specification is a worker that wakes to receive events. This provides an event destination that can be used when other destinations would be inappropriate, or no other destination exists.
 Abstract:
 Abstract: For example, to allow the developer to decide how a page should be fetched, an event needs to dispatch potentially before any other execution contexts exist for that origin. To react to a push message, or completion of a persistent download, the context that originally registered interest may no longer exist. In these cases, the service worker is the ideal event destination.
