[Tagging] tunnel=culvert

[Gerd Petermann]

Hi,

thanks for the feedback. I think tunnel=culvert is special,
my understanding is that it implies that the water goes through
some kind of pipe. So tunnel=culvert on a node
simply implies that the waterway is below the road,
no layer tag is needed.

On the other hand, the wiki "disallows" to use tunnel=* on a node.

What would be in the tunnel? the waterway or the highway? how would
the layer= apply?

In this case, the highway and the railway share the same level.
