Just to add a bit of additional information: the *bare minimum* is
rel="license"; that says "this resource is made available under the
linked legal tool".  We think adding information about the work,
publisher, and territory adds additional value and clarity.  For
example, it provides easy to find information if someone wants to cite
use of your work.

Actually putting it in an HTML comment is not advised.  Parsers can and
do throw those away.  If you don't want it to show up for users, you can
always use CSS to hide it.

Let us know if you have any more questions.
