[Nsi-wg] authority and delegation of authority in NS (Actor?)

[Chin Guok]

Hi all,

I revised the NSA functional component document and essentially made it 
very generic.  After talking with Inder, I realized that this document 
should give us a VERY brief overview of the NSA, and as such, all it has is 
a block diagram and descriptions of each component.  The focus of this 
document is to support the NSI architecture document and not take away from 
it.  I've removed all the MAY/MUST statements because those should really 
be in a separate NSA architecture document, if we plan to create one.

I noticed that the diagrams from Joan and Tomohiro had the notion of a 
aggregator/coordinator.  In the NSA functional component block diagram, 
that function is supported by "Resource Management".  I'm open to ideas on 
where this should go.

Please review it and feel free to comment (there are some inline).

Thanks.

- Chin
