Hi Jimmy,


> [Jie #2] I think we are talking about different solutions. In one possible solution, an indicator in the packet could just indicate the existence of PSD, and the NAIs are carried in the PSD. This is different from the solution you mentioned above. The framework should be generalized to include different options.


There is no need for such an indication if that is defined by the solution.  Haoyou’s proposal requires no indication that there is PSD. It is inherent in the solution. There is one LSE of NAS and that’s sufficient.


> [Jie #2] OK. But my point was also about making ISD optional in the network actions. The cunin rrent text in sections 4 says that ISD is mandatory, while PSD is optional. My suggestion is to make ISD optional in this section. 


You have misread.  Section 4 lists the number of things that a network action must have.  One of the things in the list is: "The number of LSEs of in-stack data and its encoding.”  Zero is a number.
