Well sure. It IS outside the page. I was thinking of pointing that out as well. I don't think that's a foul. Of course there is a fancy term to describe the practice of alluding to unspecified references (so common in song, film and literature) but it's not coming to me. (For example, I knew nothing about the "terrorist fist jab" story until after the fact, but that's just part of the intellectual pretense. No real harm in it.)
