I agree with this interpretation (but I'm not sure how we are to understand that it was "resolved"). There's another wrinkle to consider: in the above example, suppose that v1==v2. I think we then have: ( R, sp1, v1 ) ( R, sp2, v1 ) ( R, p, v1 ) #g ------------------------------------------------------------ Graham Klyne Content Technologies Ltd.
