Characteristic optical features in the far-infrared conductivity of YBa2Cu3O7- crystals have been studied as a function of doping. We focus particularly on a reflectivity edge near 435 cm-1 which we find to be both insensitive to carrier concentration (i.e., Tc), and present in the normal state of some samples. These results place tight constraints on possible interpretations of this feature.
