without commenting the semantic of the point, I would like to say that the notation itself should be taken into account. PlaneMad wrote : turn:lanes:backward=none|none|none when rickmastfan67 wrote for the value itself : “none;slight_right” & “slight_left;none”.

Shouldn’t we agree on how to store the info ?

What I saw is that, in Potlach, the fields that contain a list of values with a “;” separator appear as errors/alerts. Therefore, I would recommend agreeing on using the “|” as the standard separator… as long as it doesn’t appear as well as an error in Potlach !!
