I critisized this quite often in the past.... Thanks Felix - that's what I wanted to know. I obviously overlooked your previous complaints! The style rules you present do look quite unwieldy - perhaps it's possible to simplify by setting initial defaults, and using those to allow revising downwards: /-------- | highway=motorway { add mkgmap:road-speed-class = 7 } | highway=trunk { add mkgmap:road-speed-class = 6 } | ... | | maxspeed:practical=* { set maxspeed=${maxspeed:practical} } | | maxspeed=* & mkgmap:road-speed-class > 1 & maxspeedkmh() <= 5 | { set mkgmap:road-speed-class = 1 } | maxspeed=* & mkgmap:road-speed-class > 2 & maxspeedkmh() <= 20 | { set mkgmap:road-speed-class = 2 } | ... \-------- Is there any reason why that wouldn't work?
