// 1. Publicly dereferenceable URIs, such as HTTPS URIs, with their authority belonging
|
|
// to that of their originating server. (Publicly facing content SHOULD use HTTPS URIs).

// 2. An ID explicitly specified as the JSON null object, which implies an anonymous object
|
|
// (a part of its parent context)
