No it isn't, and the reason is we do not want to bring the development
to a complete halt :). Our charter is

	Enhancing the performance of virtual devices by standardizing key
	features of the VIRTIO (Virtual I/O) Device Specification

Our job is thus to facilitate development by standardizing where it's
helpful.

If we start asking people to write out a formal spec for any tiny
change before they can release code, development will stop and
performance will suffer.

And it's a balance: it should be clear what is going on,
and if people can write it rigorously without confusing
matters, it is helpful.

But we don't want something like e.g. the C or C++ language spec,
where you can read all of it and still have no idea how to use it.

No but it's ok for normative sections to refer to the non-normative
ones.
