You could describe it that way, but that's still assuming that the role of "Advertiser" is required as a significant architectural component. It could be for a particular EXTENDED architecture, but I don't think it's needed or desirable for our BASIC architecture. I think the scenario described in http://lists.w3.org/Archives/Public/www-ws-arch/2002Oct/0072.html helps make this clearer. (That scenario was actually inspired by the business need that Roger Cutler described at our last F2F, incidentally.) -- David Booth W3C Fellow / Hewlett-Packard Telephone: +1.617.253.1273
