How to remove id="node-[nid]" with Display Suite? How I can remove the node id when I override a node layout with Display Suite?

In some (old) how-to I noticed that the id node is not present when a node layout is overridden with DS.

i.e.: from this 

&lt;div id="node-1" class="ds-1col node node-page clearfix clearfix view-mode-full content clearfix" typeof="foaf:Document" about="/node/1"&gt;


to this

&lt;div class="ds-1col node node-page clearfix clearfix view-mode-full content clearfix" typeof="foaf:Document" about="/node/1"&gt;


Thanks
Below code is quoted from template.php of Tao.

/**
 * Implementation of preprocess_node().
 */
function tao_preprocess_node(&amp;$vars) {
  $vars['hook'] = 'node';

  $vars['classes_array'][] = 'clearfix';

  $vars['attributes_array']['id'] = "node-{$vars['node']-&gt;nid}";

  ...


The ID is added by this line.

$vars['attributes_array']['id'] = "node-{$vars['node']-&gt;nid}";

You can override it by implementing the same hook function in template.php of your custom child theme.

/**
 * Implements hook_preprocess_node().
 */
function mytheme_preprocess_node(&amp;$vars) {
  unset($vars['attributes_array']['id']);
}
