better check for crossing highways and waterways

[skyper]

Atm validator only checks for layer=* for crossing highways and waterways. This leads to bad tagging as you get validator quiet by simply adding a layer tag to one of the crossing ways.

• we need a check for bridge=* or tunnel=* both with value but not "no".
• we need better wording of current layer check and exclude layer=0.

That problem also bothers me; when the waterway has a tunnel tag, or when the highway has a bridge or ford tag, and, in both cases, this value is not no, the validator shouldn't complain IMHO.

Replying to Penegal:

No, we need at least one layer=* and one tunnel/bridge=* where layer=0 and tunnel/bridge=no do not count.
