[Nsi-wg] NSA functional components v2.5

[John Vollbrecht]

Hi Chin --

I agree that it should not be be part of the formal NSI spec, but  
perhaps as an implementation of IDC or other services.  I also agree  
that workflow specifics are not useful for architecture doc.  I think  
probably also not useful for the protocol doc.
