Validator complains about forward/backward roles in public transport routes.

[pl71]

What steps will reproduce the problem?

1. Create relation with type=route, route=bus, public_transport:version=2
2. Insert a way as a member with role 'forward' or 'backward'.
3. Select relation and run validator.

What is the expected result?

No warnings.
Roles 'forward' and 'backward' are included in the wiki and indicate which way bus is running. We have separate relations for both directions of the bus service.

What happens instead?

Warning from validator: "Route relation contains a 'forward/backward' role"

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