OK, now I understand which one you meant, but I think I've lost the point.

It seems like just a neutral fact, from where I sit. If you're querying some service and you don't know what dataset(s) it uses, life is hard. That's what SADDLE is/was all about. I hope we get this round of specs done soon enough to get to that part of the design space. -- Dan Connolly, W3C http://www.w3.org/People/Connolly/ D3C2 887B 0F92 6005 C541 0875 0F91 96DE 6E52 C29E see you at XTech in Amsterdam 24-27 May?
