In case someone else is interested in the solution: in the relations file, I added: boundary=administrative & admin_level=* { apply role=admin_centre { set is_province_capital='${admin_level}'; } } And then in the points file: ... place=city & population > 199999 & cityxx!=yes {set cityxx=yes} [0x0500 level 4 continue with_actions ] place=* & is_province_capital<5 & cityxx!=yes {set cityxx=yes} [0x0500 level 4 continue with_actions ] place=city & population > 99999 & cityxx!=yes {set cityxx=yes} [0x0600 level 3 continue with_actions ] place=* & is_province_capital<6 & cityxx!=yes {set cityxx=yes} [0x0600 level 3 continue with_actions ] place=city & population > 49999 & cityxx!=yes {set cityxx=yes} [0x0700 level 3 continue with_actions ] place=* & is_province_capital=* & cityxx!=yes {set cityxx=yes} [0x0700 level 4 continue with_actions ] place=city & population > 9999 & cityxx!=yes {set cityxx=yes} [0x0800 level 3 continue with_actions ] ...

How can provincial capitals be detected by a style rule? I want to show them at low zoom level, even if their population is rather little.
Example: Phangnga town (South Thailand) has a population of some 10,000 people, but it is the capital of Phangnga province (see http://www.openstreetmap.org/browse/node/984029824). There is a relation for the province boundary: http://www.openstreetmap.org/browse/relation/1908799 which has Phangnga set as its admin_centre; admin_level = 4.
I tried in the points file:
place=* & mkgmap:admin_level4=* & cityxx!=yes {set cityxx=yes} [0x0100 level 6 continue with_actions ]
but that does not help: Phangnga city is shown at a high zoom level only, instead of at the same zoom level with Bangkok (ok, that's not useful, I do so temporarily to find out how things work). I tried place=city or place=village instead of place=*, same result.
Only
place=* & is_capital=province & cityxx!=yes {set cityxx=yes} [0x0100 level 6 continue with_actions ]
works as expected. Fortunately, a mapper added the is_capital tag to all Thai province capitals just a few days ago...
But I think using the relation is a better option. Only: how can I do that?
Tried that with: mkgmap 2724, Java 7 u40 (64bit), Windows 7 (64bit)
Thanks for your hints.
