In case that I grabbed points and polygons files that I had already modified, I included both before and after versions as well as a patch file for each. I never really liked the cities, towns, villages, suburbs, and hamlets handling. Now, they are by size only. In the USA, the difference has more to do with legal privileges than anything else. There are such entities with populations over 20 million: Shanghai, Beijing and Lagos and there are extant entities with names and no recorded population. They are often called ghost towns. In some states, they even have legal protection. I wanted to break out places of worship by religion for at least some of the major religions. I can supply icons for them. Making icons is easy for me. amenity=place_of_worship & religion=christian [0x2c0e resolution 24] amenity=place_of_worship & religion=muslim [0x2c0d resolution 24] amenity=place_of_worship & religion=jewish [0x2c10 resolution 24] amenity=place_of_worship & religion=buddhist [0x2c0f resolution 24] amenity=place_of_worship & religion=hindu [0x2c1f resolution 24] amenity=place_of_worship & religion=bahai [0x2c1e resolution 24] amenity=place_of_worship [0x2c0b resolution 24] Therefore, I changed the code in this line to move that item out of the block of codes that I am using. tourism=* & tourism!=no & tmp:stopMopUp!=yes [0x2f00 resolution 24] I used Wolfram Mathematica (mostly, just because it was convenient) to process the style files and some lists from the Maps Tool Kit to see what codes are available and which mkgmap style files were using. I attached that file as well in case it may be of use to you. I separated prisons and military areas in both points and polygons.
