As Harlan indicated we had an initial agreement based on early drafts of NTS; however, time moved on, the NTS draft went in a radically different direction that where it started, and those agreements never gained the full consensus of the working group. So, we are where we are now, and we need to figure out how to efficiently and effectively move forward.
