        <dd>This optional property can be used to pass in any of the options supported by the underlying
            library used to convert to and from XML. See <a href="https://github.com/Leonidas-from-XIV/node-xml2js/blob/master/README.md#options" target="_blank">the xml2js docs</a>

    <h3>Details</h3>
    <p>When converting between XML and an object, any XML attributes are added as a property named <code>$</code> by default.
    Any text content is added as a property named <code>_</code>. These property names can be specified in the node configuration.</p>
    <p>For example, the following XML will be converted as shown:</p>
    <pre>&lt;p class="tag"&gt;Hello World&lt;/p&gt;</pre>
    <pre>{
  "p": {
    "$": {
      "class": "tag"
    },
    "_": "Hello World"
  }
}</pre>
