I very much agree with this and I think that it underlies part of
our differing views on the delineation between deliverables
2 and 3.

UNIS was always multi-layer and we took advantage of the
namespacing technique from the NM-WG measurement stuff
to accomplish that.  I think that's why I see the support for the
multi-layering as being present in the base, with the details of
the layers themselves being in deliverable 3.
