No!

I have also been pondering using <img rel="nhrefs:role"
src="http://nhrefs.org/authoritative"/> (where an icon could be hosted
at http://nhrefs.org/authoritative) or <a rel="nhrefs:role"
href="http://nhrefs.org/authoritative"/>. I kind of like these
alternatives but wouldn't like to reopen the debate of the confusion
between resources and URI references!

Oh, yes, thanks.

Yep.

Thanks,
