I've seen both in official looking documentation. 'Top Tier fuel shall have E10' and 'Top Tier fuel will always be tested with E10 to ensure that it is compatible.'
Whether or not it's required doesn't matter. Eventually All fuel will have E10 so long as there are politicians to pay off.
Michigan MCLA Section 290.644
E0-E10 does not need to be labeled.
