http://philip.html5.org/data/profile-values.txt - looks like tens of 
people use @profile for DC.

http://philip.html5.org/data/link-rel-rev.txt - looks like hundreds of 
people use rel="schema.DC".

http://philip.html5.org/data/meta-names.txt - looks like thousands of 
people use <meta name="DC.*">.

So, people don't seem to follow the profile requirement much.

(Further interpretation of the data is left as an exercise for the reader.)
