http://schema.org/docs/gs.html#schemaorg_expected says: "When browsing the schema.org types, you will notice that many properties have "expected types". This means that the value of the property can itself be an embedded item (see section 1d: embedded items). But this is not a requirement—it's fine to include just regular text or a URL. In addition, whenever an expected type is specified, it is also fine to embed an item that is a child type of the expected type. For example, if the expected type is Place, it's also OK to embed a LocalBusiness." so they aggree with Hugh.
