Development of Creative Commons licenses

["David Isaac" <aisaac0 AT verizon.net>]

Questions arose on the docutils-develop list
http://sourceforge.net/mailarchive/forum.php?thread_id=7032080&forum_id=8812
as to the applicability of the public domain license
http://creativecommons.org/licenses/publicdomain/
outside of the US.  Specifically it was suggested that
certain rights cannot be given away this way in France and
Germany, and that these rights may or may not be relevant to
the intent of the license.  Question #1: is the CC Public
Domain license able to accomplish its intent outside the US
and specifically in France and Germany?

A secondary matter arose: the public domain license contains
no disclaimer, in contrast e.g. to the GPL.  So question#2:
shouldn't the CC Public Domain license include a disclaimer,
or is there something about the public domain that makes
this irrelevant even for identifiable authors?

Thank you,
Alan Isaac
