Joel,

What I understood from Jerome's answer is he is OK to cite the liaison document in the generic use case document (+ some text): 

"JM: And such citation/pointer (+ a few words of context) would become *the* reference for fixed-broadband use cases, removing the need for a specialized I-D in this respect. "

There is no need to edit a specific use case document only for the sake to have an IETF stamp on it.

I'm sure we can adopt a similar position for the 3GPP case.

Cheers,
Med
