there are a variety of cases where this would be useful. When
you distribute a link-state topology you know you're talking
about routers and links and semantic is well-known. Same when
you advertise BGP routes or VPNv4 routes or whatever... the
protocol has the semantic you need to consider.
In ALTO you have the necessary bits to tell if cost is based on
routing or air miles or others but you don't really know what a
PID is (other than a bunch of addresses).

yes, I _tend_ to agree... until we find disagreement of course ;-)
