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

}
This is how it works:
{
"type": "MultiPolygon",
"coordinates": [
[
{polygon},
{hole},
{hole},
{hole}
]
]
}
Not like this:
{
"type": "MultiPolygon",
"coordinates": [
[
{polygon},
[
{hole},
{hole},
{hole}
]
]
]
}
Here's an example!
