RDFa in the deed describes the corresponding license, and cc:Notice is a
cc:Requirement which is in the range of cc:requires which has a domain of
cc:License. A specific copyright notice would be pertinent to a licensed
work -- if this were called out with RDFa, perhaps dc:rights or another
refinement(s...there are potentially notices of copyright, license,
modification, warranty disclaimer)  thereof, it'd go in the HTML published
with the licensed work.

If I were writing an automatic remixing tool I'd go with "...it may be
reasonable to satisfy the conditions by providing a URI or hyperlink to a
resource that includes the required information." -- hyperlink to the
publisher's site, possibly including various notices in languages I can't
discern, and archive that page if you want to do something extra. You can't
count on anyone to properly annotate such notices anyway, so a tool that
looks for them can't be foolproof. You can pretty much count on them not
being properly annotated, as title and creator name usually aren't despite
being in the CC chooser forever. IANAL etc.

Maarten is right that the cc:Notice annotation ought be added back to the
deed. I might not add it to the text concerning indication of modification
as notice isn't specific only to that, but that's very close to right. IMHO
etc.
