This is going to break things crazily. The INT values correspond to different things when we are creating relationships. It is not just `TRUE` or `FALSE` in this sense as they correspond to the switch here: https://github.com/Islandora/tuque/blob/1.x/FedoraRelationships.php#L297-L316. The docs need to be updated to state that it is in fact not a boolean and perhaps elaborate on the types.
