Is it ok if you not to use: class="ui-content" in listview

Is it ok if you not to use ui-content for your listview ? :

The usual way:
  1. <div data-role="page" id="index">
  2. <div data-role="header">
  3. </div>
  4. <div role="main" class="ui-content">
  5. <ul data-role="listview">
  6. <!-- listview content -->
  7. </ul>
  8. </div>
  9. <div data-role="footer">
  10. <h4>Footer</h4>
  11. </div>
  12. </div>

What i'm using:

  1. <div data-role="page" id="index">
  2. <div data-role="header">
  3. </div>
  4. <ul data-role="listview">
  5. <!-- listview content -->
  6. </ul>
  7. <div data-role="footer">
  8. <h4>Footer</h4>
  9. </div>
  10. </div>
Is it ok to use it like that or am i breaking something ?
