[wp-docs] Codex license: CC better than GPL?

[Kaf Oseo]

Have the points raised here:

http://at.or.at/hans/blog/2007/01/14/problems-with-cc-attribution-clauses/

ever been clarified? Seems important, especially since CC-BY-SA is being 
recommended as the replacement to GPL. Attribution on a "document" such 
as the Codex could definitely be unwieldy under CC-BY-SA, considering 
the numerous (and often untraceable) authors involved in the work.
