Development of Creative Commons licenses

[Rob Myers <robmyers AT mac.com>]

In by-sa-2.0:

4a allows the removal of references to the author from a 
collective/derivative work if the licensor requires it:

"...upon notice from any Licensor You must, to the extent practicable, 
remove from the Collective Work any reference to such Licensor or the 
Original Author..."

But 4c requires that the licensor be acknowledged appropriately for the 
medium as well as copyright notices being given:

"You must [...] give the Original Author credit reasonable to the 
medium or means You are utilizing by conveying the name [of the 
original author] [...] at a minimum 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"

I assume that a credit is different from putting someone's name on the 
cover of a book. Which would explain Vriginia Andrews. :-)

I note that in either case the copyright statement must remain intact.

In either case (with or without this clause of 4a being used) credit 
and the copyright will always remain in the small print of the credits 
or legal section of a work. Is this correct?

I.E. without the removal clause of 4a, the author is requesting that 
their name appear somewhere like the cover or index (for book or CD), 
in the title page (book), in the start credits (for film or TV), on the 
posters (events, film), or some similar high-profile location. Whereas 
with the removal clause they are not requiring such high-profile 
acknowledgement, but 4c means that they still get mentioned in the end 
credits or the small print. Is this correct?

This is clear in the legalese (IANAL), but I think it might end up as a 
FAQ ("I have to remove all reference, but I have to put their name in! 
Which is it?")...
