The slides that I sent out jan 16 include the updates from the breakout session that I chaired. If useful, i can take that and turn it into text. also, to dan, i suggest that the presentation that jeff gave link to the updated presentation that I sent. what i sent is just an update to the presentation jeff gave from our group. deborah Jeff Heflin wrote: > Hello, > > On Jan. 17, I asked for the chairs of the use case groups to provide > input for the Requirements Document.
