Dave Winer placed one of the RSS specs under a CC Licence.
Now he wants to stop one particular group producing a revised spec.
So he’s asking how to do this, phrasing it as a dispute about a work under the license.
Modulo moral rights you can’t control how people use the work. And even if you could, they could just produce a new document for the spec.
This isn’t a problem with the licences. It’s a social issue.
