[Tagging] Status of oneway=cw oneway=ccw

[s8evq]

Hopeful to come to a conclusion, I would like to propose to edit the Wiki with the following:


Current text on page route=hiking:
oneway 	yes/no/cw/ccw 	(optional) Use oneway=yes to indicate that the route is to be walked in only one direction, according to the signposts on the ground
proposal: It might be useful to indicate if the route is marked in the clockwise or counterclockwise direction, i.e. oneway=cw or oneway=ccw. 

Changing to:
signed_direction=yes (optional) Use signed_direction=yes to indicate that the route is to be walked in only one direction, according to the signposts on the ground. The ways within the relation should be ordered, as they are used to determine the direction of the signposts. It's prefered to not use oneway=yes anymore, as it could cause confusion with oneway=* as a legal restriction. (as discussed on the tagging mailing list (insert link))

This changes could also be applied on route=foot and route=bicycle

Comments?

Sarah remarked: "An unsorted route is not wrong, it's only less precise. Maps can show it without issues including waymarkedtrails. It just can't give you some advanced features."
