(By David Inman and Marine Vuillermet): "This is the same feature formulated as Chapter 41 in WALS (Diessel 2013) and as NP305 in SAILS (Krasnoukhova 2016). ❡
It is important to note that this feature only documents the number of distinctions made, and not other information which may be relevant to that number. For example, languages may differ in the number of deictic centers present in a system: i.e. distance from one deictic center: near (to the speaker) vs far (from the speaker); or distance from two deictic centers: near the speaker vs near the addressee vs far from both."
