[Nsi-wg] New state machine with two phase reserve and modify

[Chin Guok]

That is correct, the general trend of thought was consistency. Because 
reservation and modify are reasonably similar, they should have similar 
workflow processes.  At the meeting in Delft, there were folks on both 
sides of this argument (have a similar workflow process for both 
reservation and modify).

I am not hung up on the two phase reserve since the existing model does do a pseudo two phase.  I absolutely do believe we need a two phase modify though, otherwise things can get extremely pooched,
