That sounds reasonable.

s/“…Creative Commons Attribution-ShareAlike 3.0 specification”./“…Creative Commons Attribution-ShareAlike 3.0 license”./

I wonder if it wouldn’t be useful to also throw in language here about CC-A-SA: “we hereby license our contribution to the OAuth specification under the terms of the Creative Commons Attribution-ShareAlike 3.0 specification”.

Then, the text of the spec could also have the CC-Attribution Sharealike spec for the spec itself (as opposed to the contributions which make up the spec).

However, someone has to own a copyright… it could be jointly owned by the authors I suppose. Enforcement is a pain (i.e. enforcing the ShareAlike and Attribution terms)… something like © OAuth specification authors, Some Rights Reserved and a reference to the correct CC license.

Pelle’s change to the introductory line is good.
