A little more about Tom's terminology and I shall cease discussing more about 
copyright than you probably ever wanted to know.

 - Dennis

Transfer of copyright is different than licensing a copyrighted work.  There 
are exclusive rights that obtain to copyright holders.  A copyright holder can 
license some or all of those rights without surrendering the copyright itself. 
Absent such a license, exercise of an exclusive right by anyone but the 
copyright owner constitutes infringement.  Some infringements are defensible 
as "fair use" in some jurisdictions, but only judges decide whether the 
defense succeeds.

In the example given by Tom below, (re-)distribution of the documents by TDF 
is done under the CC-BY-SA and it is not a relicensing.  It is done under the 
original license.  And communication of the same license to the recipients is 
done under the original license.  Were the TDF or its contributors to make a 
derivative work, the CC-BY-SA requires that derivative to satisfy the 
Share-Alike requirement.  (It is a form of copyleft.)  Any added copyright 
would apply to the new material and its combination with the original.  But 
the original copyright is intact: You can't copyright the parts of a work that 
are not your own independent creation (unless you've been transferred that 

Finally, note that the copyright holder still holds all of the original 
exclusive rights and is not restricted by the license granted others.  That is 
how Sun, which held the copyrights to, was able to 
privately-license the code base under different terms than the LGPL that was 
granted to the general public and used on the open-source 
distributions.  One feature of reciprocal licenses that I favor is the fact 
that the recipients have all of the same rights that the copyright owner has, 
apart from the ability to transfer the copyright itself.

Hi :)
Ahh, i thought that when the team publishes a document the individuals CC by 
SA licence is then re-licensed under a new CC by SA licence as the original 
licence allows?

Also, "Hey that's not my glass!!!  Mine was bigger!!  And it was full!!" 
(quote from THHGttG, thanks Zaphod :) )  I might have missed a few ! marks.
Regards from
Tom :)
