comment Dual of the empty function
Thanks for the clarification. In hindsight this was quite a silly question; I essentially ignored the contradiction that arose from the $\exists$ part of $\forall x \in X, \exists y \in Y$ s.t. $(x,y) \in f$

comment Do there exist interesting binary relations satisfying reflexivity and symmetry, but not transitivity?
Thanks! This was the clarification I was more or less looking for; I'd initially thought that the relation might represent those directed graphs with an identity edge at each vertex and two (opposing) edges between each vertex where the relation holds; your representation is much cleaner.
