title: How to define swagger property that is an unknown name?
body: <p>I need to define a swagger property that doesn't have a known name.</p>
  
  <pre><code>{
    "type": "object",
    "properties": {
        "?????": {
            "type": "array",
            "items": { "$ref": "#/definitions/ModelRelease" }
        }
  }
  </code></pre>
  
  <p>The ????? portion of my definition is an integer of an unknown value. Any ideas?</p>
