Daniel was right, though. Mapnik doesn't see that data as ways and
relations. Both ways and relations are represented as lines in its db.
Relations are 'flattened' during an import with osm2pgsql, and mapnik
handles both of them exactly equal.

The *way* renders z9-z11. The *relation* renders z11+.

> admin_level=6 aren't rendered until z11
Both the *way* and the *relation* render z11+.
Aren't overlapping* boundary renderings fun? :(
* See my previous reply.
