[Nsi-wg] Notification queries.

All, It has been a struggle to keep enough focus this week to get this completed. Switching timezones is not helpful to one thinking clearly. I have attached a discussion document that presents the two original concepts discussed on the NSI call and an optimization to each. I wanted to make sure I captured both so people do not think one was ignored. I believe the solution I have recommended (with hallway agreement from Chin and Tomohiro) it the best short term option. I will have the completed WSDL ready to go so it can be committed upon agreement this week. John
