Ah, no, in fact, I didn't see that.

I suppose that's sufficient, but...

I can't parse that. I don't really like the

I have 2 arms. But I am not my two arms.

Suggest:

	A literal is either a plain literal or a typed literal.

	A plain literal is either

	* a pair of such a string and a language tag

	A typed literal is a plain literal paired with
	a URI reference.
