Hi John,
Clear proposal, thanks!
I am halfway reading this, but have a different meeting coming up, so I
just comment on what I read.

I'm not clear on the purpose of this type of adaptation (one type
encapsulated in the same type). Can you perhaps give a example?
(slide 5)
What is the purpose of having different Service Domains in a Network
Topology? Because the STP in each services domain are of a different
type? Or to describe geographic subdivisions withing a Network Topology?
Note that the former is represented in NML using multiple
SwitchingServices, and the later is represented in NML using multiple
(sub) Topologies 'in' a larger Topology (where this 'in' is formally
defined as a 'hasTopology' relation).
PS: I now see that you answered this on slide 19. Thanks, John! I love
this proposal. My head is too blurred to due lack of sleep to really
grok every character in the example, but from a first look, it looks
very, very good!
