I did update the wiki page: http://wiki.openstreetmap.org/wiki/EN:CH:Map_Features
But I don't know what tagging is correct for the "Reitweg" in German or "allée d’équitation" in french. Because a OSM bridleway may be used by bicycles and pedestrians according to http://wiki.openstreetmap.org/wiki/Tag:highway%3Dbridleway "intended for use by pedestrians and horse riders"
Any suggestions?
