Thanks for your efforts. Two points:

- Should the level tags be subsequent numerical values, or the level
names signposted in the building (for instance in the lifts)? In
England, levels are often named basement/lower ground/upper ground
floor. In Germany, I have seen buildings that distinguish floor 0 and
floor -0. If a building starts with for instance Ground, Mezzanine,
Floor 1, Floor 2, then it might be confusing to use levels 0, 1, 2, 3
for that, as then each level key would be off by one with the signed
level. Why not use level for signposted levels and layer for a
numerical order?

- What is the reason for using indoor=corridor rather than
highway=footway and stairs=* rather than highway=steps? Can a way have
both tags? Sometimes routing through shopping malls is optimal even
for long-distance foot routing, so it would be nice if regular routers
could keep make use of such footways.
