What about situations where the level and the signed level don't match? Im not trying to spatially locate the building for 3D rendering - i just want to know where to head in the mall. I got lost at Kasuga station, because there were exits labeled 1,2,3,4,5,6 and A1,A2,A3,A4,A5,A6. I wanted 6, but followed A6. i just want to know what ref i should follow to get where i am going. Having a floor:ref=* that says "tell the user my shop's floor location is "mezzanine" is more useful than "level=1.5". The signs and elevator will say "Mezzanine". A lot of places have alternate floor names (skylobby 4, P3, B2, observation deck, "450" - height in meters off the ground for the Tokyo skytree floors - since there are only 6 or so "levels" in the 634m structure. There are restaurants, gift shops, and other amenities up there. Nowhere does it ever mention a number relating to "level". I imagine that 99% of most structures follow the standard model and basic level=floor location structure, and it is not needed for them - but almost all of that other 1 percent is in large public venues where public visitors would be interested in the information - so a solution should cater to solving the problems presented by this 1 % because it will be an immediate problem for mappers, as public and interesting buildings are more likely to get more detailed mapping, and more and more detail is added to more and more objects in OSM. Also, to go back to my example, Kita-senju station is maybe 9 levels covering 3 different station sections - B2-7(?), with shops in the station from basement to 2 - but then there is a whole mall on top covering the rest. They might start measuring the map where it begins on the 2nd level, not the actual levels of the building, or have some odd naming scheme. Being able to refer to the location **as labeled on the user information signage** is very important - even if that doesn't line up with the level=* of the overall structure. Which is why i suggested level:ref= as it is the reference for the level it is on, not the physical level it is on. Which for these 1% structures, is the difference between useful and garbage information.
