Yes.  For declarations with the same weight, origin and
specificity, then the order is used, and the latter wins.
At least, that's what the spec says (both CSS1 and 2).

I think adding the role to the class should be turned on 
by a parameter.  Some people won't want their roles
showing up in their HTML.  And there may be cases
where it messes up existing CSS stylesheets.
