"Gluten is a protein that is found mostly in wheat but is also present in other cereal grains, including rye, barley, oats and buckwheat.  It actually is a crude mixture of two other proteins, gliadin and glutenin.  Grains that do not contain Gluten are rice, amaranth, millet, corn and quinoa."^^<http://www.w3.org/2001/XMLSchema#string>
