Juergen: 

Yes, we seem to disagree on the value of making it hardwired in the model.
For me, the value is a common understanding of deployment distribution such
as the route-views.   Since the operators argued strongly for this point, I
think the best idea is to get it working in code and then see if the
deployment matches the requests.

Sue,

I still do not see why the 'mode of exposure' of data benefits from being
hard-wired in the data model. For me, it is a situational and deployment
specific question. But I shut up here since I aired this concern before (and
we simply seem to disagree).
