eski! consider this; when nationality is a psychogeographical quality this implies that nationality is a shattered all over the place. This opens up the possibility that your nationality is an array of PML data that descibe places where you feel at home, or are at least attracted to. Once you have established you nationality like this (which of course can change over time both because the place changes & because the things you are attracted to change) you can locate your homeland abroad by matching your PML nationality to the existing datasets. Nationality as geocaching!
