title: Item Descriptor Inheritance in ATG for "contactInfo"
body: <p>I am trying to inherit the "contactInfo" item and create a new item descriptor.. Something like this as given below..</p>
  
  <pre><code>&lt;item-descriptor name="testContactInfo" super-type="contactInfo"&gt;
      &lt;table name="test_contact_info" type="auxiliary" id-column-name="contact_id" shared-table-sequence="1"&gt;
          &lt;property name="fixedlinenumber" column-name="fixed_line_num" data-type="string"/&gt;
      &lt;/table&gt;
  &lt;/item-descriptor&gt;
  </code></pre>
  
  <p>I get the following error when i start the server.</p>
  
  <pre><code>14:19:52,856 ERROR [ProfileAdapterRepository] Error parsing template: atg.repository.RepositoryException: Your item-descriptor definition for testContactInfo has super-type contactInfo but no sub-type attribute.
  </code></pre>
