I can see two solutions:
1.- Add data for the renders: use a border_level tag to specify that. So a
border_type=canton with border_level=5 in one country will render the same
as border_type=department with border_level=5 in other. Each country
community should define which border_level matches which border_type,
starting from some common types for all countries (like border_type=country,
2.- Define the type classification for each country, and let the renders
guess the right renderings according to the border_type and lat/lon.
