[OSM-talk] railways/roads/canals/rivers/etc. inside buildings

[Robin Paulson]

a situation has come up, where i've been mapping some railway lines
that go through a maintenance shed. the problem is, the railway is
drawn on top of the shed, rather than shown dotted too imply it's
underneath/inside. is there a tag i could use, to show that it's
inside? something like the tunnel tag
