Another related issue -- maritime disputed borders. In the case of Crimea,
the disputed border with Russia is over water, thus not showing clearly in
many renderings, and over land with Ukraine, showing as a solid line - thus
appearing to side with the Russian interpretation.

A while ago Paul Norman wrote osmborder tool to help with the disputed and
maritime border rendering [1].  His tool mostly uses disputed=yes . The big
problem with rendering was that multiple borders
(city/county/state/country) were all overlapping one on top of the other,
producing a solid line. Instead, when drawing there should always be just
one line with the lowest admin level.
