[Tagging] Bus relation - circular route - report says not closed

[Warin]

Hi,

I have made a new relation: 7258397 - a bus route 686 that is 'circular' 
in that it returns back to the same start position and then repeats the 
same route.

Some of the route travels in both directions on the same ways, while 
other parts only use a way in one direction.

P1) JOSM validator reports that the relation is not closed. Yet all 
elements appear and they are connected.

P2) Roles forward/backward are apparently no longer used, and a role to 
indicate that both directions does not exist. Yet these may assist to 
have these kinds of roles?

P3) stop_position ... left side or right side of the way? On a train 
line this probably works well .. on a road that has traffic in both 
directions with parking on both sides .. stop_position does not have all 
that much information.


Thoughts?
