Warn about direction=forward/backward on invalid nodes.

[skyper]

What steps will reproduce the problem?

1. Have an child end node or a child middle node of more than one way with [high|rail|water]way] and *[:]?direction=[forward|backward]
2. run validator

What is the expected result?

A warning about invalid values of direction for the geometry

What happens instead?

No warning

Please provide any additional information below. Attach a screenshot if possible.

See #20013 for the origin.

Replying to Klumbumbus:

I think the validator should warn if a node with direction=* is

• on a ways first/last node (possible in mapcss)
• belongs to two different highway=* ways (not possible in mapcss)

• Only warn about values forward and backward. Other values are valid.
• Include railway and waterway in both test.
