tunnel=building_passage conflicting definition
This page had the text "not to be confused with the combination tagging of highway=footway and tunnel=building_passage, which relates to a tunnel which begins at a point outside the building and ends at a point outside the building". However the part "a tunnel which begins at a point outside the building and ends at a point outside the building" clearly conflicts with the approved definition of building passage http://wiki.openstreetmap.org/wiki/Proposed_features/building_passage#tunnel.3Dbuilding_passage]].
Currently it is not clear if there is any meaningful distinction between highway=corridor and tunnel=building_passage however it would appear that a tunnel is a way "isolated" from the building whereas a corridor is just that - many door and other ways connecting it to other elements of the building.

- I think your viewpoint is probably controversial: tunnel=building_passage has always been used for highways which are external to a building but which look absurd when rendered over the building. Anyone using this tag for indoor mapping is doing it incorrectly and vice versa. The only marginal cases I can think of is where the building passage if protected by doors, but in these cases they only connect with other ways which are not inside buildings.

- The point is, the linked proposal and current definition describe exactly how to map tunnel=building_passage and this is in contradiction to the deleted text. What you are describing is some kind of mapping for the renderer edge case.
- I am not a great friend of tunnel=building_passage, imo and by apparent intention of the author of the proposal it should have actually been covered=building_passage but was realized as tunnel ... you guess it .. as a mapping for the renderer hack. If I had some spare time I would propose covered=buidling_passage right now. RicoZ (talk) 15:05, 19 February 2017 (UTC)
