Hi James,

Because of the WG agenda shuffling, it looks like I missed your presentation on that. 
One point I wanted to discuss is how you plan addressing the comment that Toerless made at Maastricht IETF about supporting "ranges" of bandwidth (as opposed to list of bandwidths).

For memory, Dave Oran brought up the issue of Tspecs being multi-dimensional and therefore generally not directly comparable, but we want to find a way around this issue.

We think this is important to know when handling errors to RESVs.
