Wuh? We're specifying a universal font size for all media? Why not  
specify the typeface, the colour, and an angle of 23 degrees to the  
horizontal while we're at it?

The CC-BY-SA legal code actually says:

- "You must include a copy of, or the Uniform Resource Identifier for,  
this License"

- "You must... give the Original Author credit reasonable to the  
medium or means You are utilizing by conveying the name (or pseudonym  
if applicable) of the Original Author if supplied; the title of the  
Work if supplied; to the extent reasonably practicable, the Uniform  
Resource Identifier, if any, that Licensor specifies to be associated  
with the Work, unless such URI does not refer to the copyright notice  
or licensing information for the Work; and in the case of a Derivative  
Work, a credit identifying the use of the Work in the Derivative Work  
(e.g., "French translation of the Work by Original Author," or  
"Screenplay based on original Work by Original Author").

- "Such credit may be implemented in any reasonable manner;  
provided... such credit will appear where any other comparable  
authorship credit appears and in a manner at least as prominent as  
such other comparable authorship credit."

That seems plenty clear enough to me - there's no point us trying to  
rewrite it, we just need to specify our name and URI, and the URI of  
the licence.

I'd echo Tom Chance's comment (on legal-talk) that "some rights  
reserved" isn't really very helpful: it's better to actually say  

If I wanted to use OSM maps in the magazine I edit, I'd suggest the  
best form of attribution would be a standard-sized ("in a manner at  
least as prominent") picture credit of "data from  
www.openstreetmap.org, CC-BY-SA licence", and a paragraph in the  
"flannel panel" explaining in friendly language what Creative Commons  
licences are and how you can find out more, including the URL of the  
full licence.
