I am skating on thin ice here, but my understanding is that it won't  
be enough. The 'rel' attribute indicates a relationship between your  
document and the linked-to document, declaring the linked document to  
be a "license." The other bits that you are omitting, actually allow  
extracting terms such as 'publisher' and 'title' from your  
declaration. Note that if one (a human being or a program) follows the  
a href, they land up at the CC0 waiver page where they can get an  
earful re. the CC0 waiver, but have no clue as to the entity that  
actually used that waiver.

I have sent a query to CC, and I suggest you do so as well. Hopefully  
we will have this resolved rapidly. In the meantime, as I said, just  
put the whole bit inside HTML comments, with only the CC0 badge  
showing up and going through the validator.
