Summary
The layer Key can be used to mark if a way/node/area is above or under another one.
Do not use this tag to correct some render behaviour and let the output look better.
This tag should only be used for high differences that are real, like bridges over a street or tunnel under another object.
Common values are: layer=-5 to layer=5
while layer=0 is for the normal ground level and is assumed for any object that has no layer tag attached.
