## Vendor Extensions

extensions has been added.

### `x-kubernetes-group-version-kind`

Operations and Definitions may have `x-kubernetes-group-version-kind` if they
are associated with a [kubernetes resource](https://github.com/kubernetes/community/blob/master/contributors/devel/api-conventions.md#resources).


For example:

``` json
"paths": {
    ...
    "/api/v1/namespaces/{namespace}/pods/{name}": {
        ...
        "get": {
        ...
            "x-kubernetes-group-version-kind": {
            "group": "",
            "version": "v1",
            "kind": "Pod"
            }
        }
    }
}
```

### `x-kubernetes-action`

Operations and Definitions may have `x-kubernetes-action` if they
