Tip to solve w3c validation with many lists

In a site with many lists i get a Duplicate ID lcp_instance_0 error when make a w3c validation.

I dont know if this is wrong but clean all my duplicate errors of this type:

Just erase this from catlistdsiplayer

//Give id to wrapper tag
    if (isset($this->params['instance'])){
      $this->lcp_output .= ' id="lcp_instance_' . $this->params['instance'] . '"';
    }

This will take out the ids from the list, so u dont have duplicates.

I wonder if anyones knows if this is right. Great plugin
