Chris proposed
(http://lists.geojson.org/pipermail/geojson-geojson.org/2007-March/00003
0.html) this:

    "type":"Polygon",
    "exterior":{
        "type":"LinearRing",
        "coordinates":[-129.83,3.46,...,-95.47,21.51]
    }

(That would be "coordinates":[[-129.83,3.46],...,[-95.47,21.51]] now.)

Although the "interiors" aren't mentioned, it is clear that coordinates
is not three levels deep, because each value represents a single ring.
