    2. TW
    uses Workflow's Retrieve use case to 
     | 
     | 
   
   
    retrieve
    the Digital Document. 
     | 
     | 
   
   
     | 
   
   
    3. TW
    opens the Digital Document in the Digital 
     | 
   
   
    Document
    to IETM Section Converter and 
     | 
     | 
   
   
    produces an IETM
    Section. 
     | 
     | 
   
   
     | 
   
   
    4. TW
    reads the IETM Section looking for errors 
     | 
     | 
   
   
    brought
    about by the conversion process. 
     | 
     |

    any errors are found, TW corrects them.
