Yes, I was wondering the same. For the EARL values I was wondering what 
happens if someone does create an instance of say earl:Passed, and also 
provides a dc:title and dc:description. Should tools ignore these or do 
they override the rdfs:label and rdfs:comment?

Let's discuss this in a few minutes, it is general to all our documents.

<earl:Passed>
   <dc:title>Failed</dc:title>
   <dc:description>Actually, it didn't pass after all</dc:description>
</earl:Passed>

Best,
   Shadi
