    <h1>Advanced JSON Editor Example</h1>
    
    <p>This example demonstrates the following:</p>
    <ul>
      <li>Loading external schemas via ajax (using $ref)</li>
      <li>Setting the editor's value from javascript (try the Restore to Default button)</li>
      <li>Validating the editor's contents (try setting name to an empty string)</li>
      <li>Macro templates (try changing the city or state fields and watch the citystate field update automatically)</li>
      <li>Enabling and disabling editor fields</li>
    </ul>
    
    <button id='submit'>Submit (console.log)</button>
    <button id='restore'>Restore to Default</button>
    <button id='enable_disable'>Disable/Enable Form</button>
    <span id='valid_indicator'></span>
    
    <div id='editor_holder'></div>
