This kind of potential ill readily infects those "proposition-expanding" state- ments as well. A sentence like 'The move for cultural diversity at our universities and colleges has been in part spurred by our changing demographic student body" can certainly be considered part of an author's primary discourse that supplies propositional content. In spite of its primary status, such a sentence is very much susceptible to "misfire" if it turns out to be not true; it is also open to "abuse" if the author has no intention of backing it up with necessary evidence. If metadiscourse markers can be judged either true or false, the apparent basis for characterizing metadiscourse as being "nonpropositional" collapses.
