The specification and everything around it

The normative text is one document. The others exist so that the normative text does not have to argue for itself, apologise for itself, or keep a diary.

Application layer — not the protocol

Common Time exists because something needed it. These documents describe that something, and they are not part of the specification — a conforming implementation owes them nothing.
