(By David Inman and Marine Vuillermet): "In some languages, demonstratives additionally distinguish evidential or epistemic properties, the most common being between seen (or directly experienced) and unseen (or indirectly experienced) objects. This epistemic/evidential property can be described as a visible/invisible or a present/absent distinction. This feature considers all of these to be typologically similar and categorizes this set of properties as a visible/invisible distinction. This is designed to be compatible with the formulation made in NP306 in SAILS (Krasnoukhova 2016)."
