title: GeoJSON MultiPolygon with multiple holes
body: <p>Below I have what I'd expect is a way to create a <a href="http://geojson.org/geojson-spec.html#id7" rel="noreferrer">GeoJSON <code>MultiPolygon</code> object</a> with one polygon in it which has two "holes". </p>
  
  <p>When I use the service <a href="http://geojson.io/" rel="noreferrer">http://geojson.io/</a> to validate this object, it returns with an error <code>each element in a position must be a number</code> and it does not render, however if I remove the "holes" nest, removing one of them then it works.</p>
  
  <p>I'm looking for a way to describe a <code>MultiPolygon</code> where the polygons can have multiple holes.</p>
  
  <p><strong>I'm not looking for a way in code to create a polygon with holes.</strong></p>
  
  <p><strong>I'm looking for a way to use the GeoJSON spec to represent MultiPolygons with multiple holes.</strong></p>
