That is an excellent solution.  However, I have a couple nits to pick.

I would prefer:

          name        CDATA   #IMPLIED  -- name (or alias) of owner  --
          email       CDATA   #IMPLIED  -- email address of owner    --
          href        %URL;   #IMPLIED  -- URL for biographical info -->

as it more directly reflects what you describe.  Obviously, it would be
easy for a server to translate this into 

      <LINK rev="OWNS" title="name (email)" href="href">

and thus follow Tim's suggestion as well.
