Hi Jonathan:
The description resource will be a set of links, correct?
If so, should we say something like "the same description resource 
should be returned by the various methods"
This needs a bit of tweaking as you will sometimes get the resource and 
sometimes a URI to the resource.

I made such a comment when I first reviewed the spec and Eran was 
sympathetic to it and said
they would address it in a future draft.

All the best, Ashok
