Some month ago I proposed the feature to "double" elements already. Right now I have to use 6 style-files for each map tile to get all the elements I want. We would need a seperate file in the style-file where you can write in all features that should be checked for independantly whether or not an object has already be included (for the example this file is called "doublecheck"). i.e. imagine a street object with the following attributes: highway=track; bridge=yes; tracktype=grade1 In the style file "lines" we search for: highway=track [0x30 resolution 18] In the "doublecheck" file we search for: bridge=yes [0x31 resolution 20] tracktype=grade1 [0x33 resolution 20] In the typ we now define (for simplicity 9=transparent, 0 =yellow, 1=red, 2=black) 0x30: 11111111111111111111111111111111 0x31: 22222222222222222222222222222222 99999999999999999999999999999999 22222222222222222222222222222222 0x32: 00009999000099990000999900009999 00009999000099990000999900009999 99999999999999999999999999999999 99999999999999999999999999999999 99999999999999999999999999999999 99999999999999999999999999999999 99999999999999999999999999999999 The highway=track; bridge=yes; tracktype=grade1 Mapsource or on the PNA would now look like the following: 00009999000099990000999900009999 00009999000099990000999900009999 22222222222222222222222222222222 11111111111111111111111111111111 22222222222222222222222222222222 99999999999999999999999999999999 99999999999999999999999999999999 There is one thing to notice however. the file "doublecheck" needs to be run AFTER the file "lines" and after the file (For Polygons this doesn't matter as we have to define a "draw order" in the typfile determining what is shown on top). POI are not possible to be shown with transparency on top of each other. I would propose having the file "doublecheck" only for lines and for Polygons. The "points" file should by default allways make one POI per found indicator. So a POI with amenity=restaurant; amenity=hotel should always be put as two points into the resulting map. The order of operation in the style-file "points" will determine what shows up on the map. On Mouseover however we can see all POI - and also searching for restaurant as well as hotel we are able to find the amenity=restaurant; amenity=hotel. Inside the "points" file we would need a "break" command however. Imagine a POI, amenity=restaurant;cuisine=thai;amenity=hotel. in the points file we define: cuisine=thai [0x1012 resolution=20 break amenity=restaurant) So that after finding we have a thai restaurant, we don't get the entry amenity=restaurant, but we would still get a dedicated POI for amenity=hotel. Of course I could right now achieve all this by running several style-files on each input file (objects from higher mapnames will show above objects from lower mapnames), but this takes much more time (the data has to be read to memory each time) and you end up with many more (many very small tiles, e.g. a tile showing nothing but bridges and tunnels) tiles than needed.
