RE: [xri] [Fwd: Re: Clarifying what a URL identifies (Four Uses o f aURL)]

Thanks Peter,

This was exactly the point I was trying to highlight during the call and
which you have described so succinctly. I agree that the right place for
this is in the requirements draft but also believe that a high level
synopsis should be incorporated into the charter as a way of conveying to
our audience our appreciation of the gaps and overlaps with other work in
the same space.

I think that the two documents will probably evolve in parallel. I'll take
responsibility for the charter piece of it.

Marc
