Nick I'm very much with you on this. In fact, I have already started using designated= tags as I think they solve a number of problems that have been discussed here. If there are rendering advantages as well, so much the better. You're more experienced in the mysterious ways of OSM than am I, so I assume that you'll start some sort of polling / voting procedure?

I now think the designation tag is a good thing as it simplifies the Mapnik XML rendering rules significantly. It could always be internationalised, for instance in the UK it could be "public_footpath", "public_bridleway", "permissive_footpath" etc, while in other countries it could be the equivalent. This could then be combined with tags representing the type of way, e.g. track, footway and path (treating the last two equivalently for the moment) and surface tags to indicate the surface. >From a rendering point of view I can envisage two layers, one for the physical ways and another to indicate where walkers/horse riders are allowed to go. The layer would show double dashed lines for tracks or single dashed lines for paths/footways, and then the second layer could have thicker transparent lines for actual rights of way (or permissive routes), a bit like the cycle map. Tracks known to be private (something the Ordnance Survey do not show, and therefore something that could be a big advantage over OS maps) could be overlaid by a transparent red line to indicate "do not go here".
