If the value of CRS is null, no CRS can be assumed.\n\n* The crs member should be on the top-level GeoJSON object in a hierarchy (in feature collection, feature, geometry order) and should not be repeated or overridden on children or grandchildren of the object.\n\n* A non-null CRS object has two mandatory members: `type` and `properties`.\n\n* The value of the type member must be a string, indicating the type of CRS object.\n\n* The value of the properties member must be an object.\n\n* CRS shall not change coordinate ordering.",
