There has been a long debate for whether NS belongs to service or resource, and whether to support a separate class to model NS or do service extension to support NS. It seems like that we haven't have a unified conclusion on it, which hampers the modeling work on service and resource.
Therefor I suggest the modeling subcommittee to start 2 vote activities for it:
- A, NS belongs to service
B, NS belongs to resource - A, Support NS descriptor internally
B, Do service extension to support NS and do not support NSD internally.
