  //   heading of the section. Note that any inner HTML tags, styles or
  //   attributes will be ignored. For example, <h1 style=".."> will be treated
  //   the same as <h1>. Only pure text wil be preserved.
  //
  // Paragraph tag: <p>:
  //   Paragraph tag can be used to wrap detailed introduction or contents. Any
  //   inner tags, styles or attributes will be ignored with a few exceptions:
  //   <br>, <strong> and <em>. Please see the phrase tag section below for more
  //   details.
  //
  // List tags: <ul>, <ol>, <li>
  //   <ul> tag can be used with <li> tag to display unordered lists, and <ol>
  //   tag can be used with <li> to display ordered lists. This is a good tool
  //   to display checklists, highlights or any other lists that fit your
  //   use-cases.
  // Example: To show a list of features of a cruise trip:
  //  <ol>
  //    <li>Wonderful ocean view and chances to play with wildlife.</li>
  //    <li>Carefully designed travel arrangements and services.</li>
  //    <li>Gauranteed lowest price.</li>
  // </ol>
  // Note that only <li> children under <ul> or <ol> tags will be converted. All
  // other children will be dropped. Also any inner tags, attributes and styles
  // will be ignored, only pure text contents are preserved.
  //
  // Division tag: <div>
  //   All supported inner tags of the <div> tag will be parsed with the rules
  //   stated above. But <div> tag itself does not mean any grouping or
  //   indenting here. Also any inner attributes and styles will be ignored.
  //
  // Phrase tags: <br>, <strong>, <em>:
  //   Only the three tags mentioned above are supported. <br> can be used to
  //   break lines in paragraphs, and <strong>/<em> can be used to highlight
  //   important text. Any other phrase tags will be ignored.
  //
  // Unsupported tags:
  //   * <html>, <header> and <body> tags are not allowed.
  //   * Any URLs, anchors, links will be striped, and will never be displayed
  //   to end-users. If you want to use photos to create a rich user experience,
  //   please use the "related_media" field below to send your photo urls
  //   * Any other tags not mentioned above are not supported (for example
  //   <table>, <td> ...).
  //
  // Important notes:
  //   * Try not to use other tags except for the supported ones mentioned
  //   above, because contents within unsupported tags will be excluded from UI
  //   rendering and may lead to undesired user experience.
  //   * Try avoid deep nested structures like more than 3 different heading
  //   levels or nested lists. Keeping the structure flat, simple and
  //   straightforward helps to create a better user experience.
  //   * If the currently supported layouts are not enough for your use cases,
  //   please contact Google with your requests and we will find the best
  //   approach for you.
