I have recently attempted to add three XC ski trails: Beaver Brook XC ski trails. The first two render properly, complete with the little XC ski icon. The third one, which joins the one of the properly rendered trails at the marker, renders as a simple generic path. It also renders as a generic path on the Pistes-Nordiques site.
My assumption is that I have made a typo in one of the piste:* tags, but I have looked at them a hundred times and failed to find the typo That, of course, does not mean that there is no typo
Strange … today it is rendering properly on the Pistes-Nordiques site (same link as in previous post) but still rendering as a generic path with Osmarenderer … Mapnik does not seem to have a special rendering for XC ski trails. Since it also seems to render the way an advanced XC ski trail should in JOSM I am ascribing the “problem” to a rendering bug, not to my tags.
