Multiple values for rel attribute

Question

Can I have multiple values for rel attributes? Like so:

Link

.. is it valid and cross

Answer 1

Actually it isn't valid according to Structured Data Testing Tool.

I tried this tonight, using the following

rel="publisher nofollow"

and it failed to validate the publisher. As soon as I removed the nofollow is validated ok again.

I thought I would post my answer, as I came across this thread after doing a Google search for the same question.
