Well according to maptk, sea is the only poly on DP level 0 (maptk 
counts from 0), while land is on 1, and all other polygons are on 2 or 
higher. Maptk makes no automatic adjustions to the levels, so if were to 
remove sea at 0, then all other polys would stay at their DP level.
The sourcecode for my typfiles is available (like my styles) here: 
https://svn.origo.ethz.ch/openmtbmap

Really bin ati.land if you don't want to have a lot of trouble and 
things going wrong. ati.land sucks regarding to extended types, and 
makes some more mistakes. If you feed my typfiles into ati.land, they 
come out completely crashed.
