maybe i'm missing a subtlety here.

i think it is possible to have three documents, X, Y, and Z.

i think that X can refer to Z as normative, and not refer to Y.

i think that Y can refer to Z as informative, and not refer to X.

am i wrong?

in other words, my belief (which may be mistaken) is that the statement

	Z is normative

has meaning only in the context of the referring document.
