Nearly, but not quite.  The above is not valid.  The following has the 
(I think) intended meaning: 

    <element name="ShipmentNo">
      <complexType>
        <simpleContent>
          <extension base="integer">
           <attributeGroup ref="attribute"/>
          </extension>
        </simpleContent>
      </complexType>
    </element>

You can't restrict and extend in a single step
