// 1. There is exactly one AccountData and it is the first frame.
// 2. A frame referenced by ID must come before the referencing frame.
// e.g. a Recipient must come before any Chat referencing it.
// 3. All ChatItems must appear in global Chat rendering order.
// (The order in which they were received by the client.)
