Excellent example! And I can see how that one is not quite obvious.

I'd say that should considered be a Notice template.

Notices tell as something "about" the page's content, they're not really part of the page itself -- this one informs readers what quality the content is. Other notices talk about different things like: this page contains spoilers, this page is not finished, etc.

I've gone more in depth on this notion of "aboutness" (or meta-information) in a recent reply on the Portability Hub's Office Hours.

BTW, next Office Hours are coming to the forums on Thursday, don't miss it. Or ask a portability question today. ;)
