[Nml-wg] Definitions of Topology, Domain and Network

[Inder Monga]

I am wondering if it is possible to combine two definitions to come up with what you would like to see
"If we had the concept of a "connected subgraph" of a domain or

for example:
Domain Topology = connected subgraph of network elements within a domain. 
Physical Topology = connected subgraph defining the physical connections between the network elements
....
