That is also quite nice, my main problem with this approach is - can we by now assume that the mkgmap:country tag is 99.9% available correctly when using precompiled bounds? [snip]
if ( mkgmap:country=DEU ) { include 'deu_highway_rules'; }
Would this mkgmap:country be assumed to be constant for all map objects? If mkgmap builds a rectangular map tile that includes a bit of Germany, Austria and Switzerland, would this include be executed unconditionally, and each rule in it would be prefixed with the condition "mkgmap:country=DEU &"? If the include statement is dynamic, what if the first objects in the OSM extract happen to be outside Germany? Would you then skip the include for all of the map tile, skipping it for the German part of the tile? If the first objects are inside Germany (mkgmap:country=DEU holds), would the rules be applied to all subsequent map objects, no matter if mkgmap:country=DEU holds for them? Marko
