Yes, that is a problem, and not just because it is not valid HTML. It  
doesn't seem to be valid XHTML+RDFa as well, as per the validator at http://validator.w3.org/check

Interestingly, W3C's recommended RDFa syntax at http://www.w3.org/TR/rdfa-syntax/ 
  also doesn't seem to pass W3C's validator.

So, now what to do? First, let's inform CC that this is an issue. I am  
sending them an email, but you should also send one to explain the  
problem and add to the feedback.

Second, perhaps the best option may be to put the entire CC0 code in  
comments, and only put valid markup visible to the validator.

Of course, you could just ignore the errors and proceed merrily, but  
that is not right. I think our feedback should help CC fix this or at  
least clarify what DOCTYPE we need to use in order to generate RDFa  
markup that passes the validator 100%. This needs to be even more easy  
and clear.

Many thanks,
