Sorry, the source xml in the example should read:

<root>
  <a>
    <xml>
      <Schema>
        <ElementType>
          <attributeType>attA-1</attributeType>
        </ElementType>
      </Schema>
    </xml>
  </a>
  <b>
    <xml>
      <Schema>
        <ElementType>
          <attributeType>attB-1</attributeType>
        </ElementType>
      </Schema>
    </xml>
  </b>
  <c>
    <xml>
      <Schema>
        <ElementType>
          <attributeType>attC-1</attributeType>
        </ElementType>
      </Schema>
    </xml>
  </c>
  <b>
    <xml>
      <Schema>
        <ElementType>
          <attributeType>attB-2</attributeType>
        </ElementType>
      </Schema>
    </xml>
  </b>
  <a>
    <xml>
      <Schema>
        <ElementType>
          <attributeType>attA-2</attributeType>
        </ElementType>
      </Schema>
    </xml>
  </a>
</root>
