      <ProcessNode select="article"/>
      <PlaceObject>
        <Textblock>
          <Value select=" $articletext "/>
        </Textblock>
      </PlaceObject>
    </Record>

    <Record element="article">
      <SetVariable variable="articletext">
        <!-- the previous contents is added -->
        <Value select="$articletext"/>
        <Paragraph>
          <Value select=" @description "/>
        </Paragraph>
      </SetVariable>
    </Record>
