Hi, I have a question about mkgmap:road-speed-class and the road_speed/road_class elemets. The documentation only writes that "mkgmap:road-speed-class" overrides "road_speed". But if I use "road_speed", what does this mean for "mkgmap:road-speed-class"? Example: highway=motorway [0x01 road_class=4 road_speed=7 level 3] maxspeed=* & mkgmap:road-speed-class!=* & maxspeedkmh() > 60 { set mkgmap:road-speed-class = 4 } Will the second rule overwrite the first one? If yes, how can I check if road_speed was already set or not? If not, will the second rule have ever any affect? This construct is used in the default mkgmap style, setting road_class/road_speed in the action block, and later according to maxspeed in inc/roadspeed.
