> One condition of all CC licenses is attribution.

There's probably a distinction that I'm not aware of but this is not true for CC0 (as stated also in the FAQ for CC0 on this same website).

They seem to draw a line between their licenses and CC0, which they regard more as a "public domain dedication tool". Truth is, you usually can't really throw something in the public domain even if you want to : CC0 is supposed to be a way to get as close as possible. Being in the public domain means your work doesn't need a license, because there is no right to license. They seem to get rid of that word for that reason (it's still a license though obviously).
