Re: [xhtml-role] List of *mandatory* values for role attributes? (PR#9631)

There is no requirement on the UA to do anything with regard to these values, so
in that sense they are all optional.  User Agents may do something smart with
them if they so choose.  What that is, that's up to them.

We will make this clearer in the spec.
