[Nsi-wg] NSA functional components v2.3

[Chin Guok]

Hi Radek, Guy,

I agree with all the comments you guys have brought up.  I'll make another 
pass at the document to clarify the points that have been brought up.  I'm 
going to be busy potentially for the rest of the week, so you may not see 
it till early next week.
