Although very early versions of RDFa (if I remember well, I was not part of the group back then) did introduce new elements, the group made a very conscious decision to express everything in terms of attributes only. (Hence the name, RDF in attributes). The reason is that adding a new element to a host language is much more demanding. It is generally true that, say, a browser will simply ignore an attribute it does not understand but will add that attribute to the DOM tree, it may screw up the presentation algorithm of a browser if it hits an element it does not understand. On the other hand, convincing the HTML5 group to add a new, RDFa specific element to HTML5 is a lost cause.
