  <description value="Specify to include list references when generating a document using the $document operation"/> 
  <!--    
    the $document operation will include everything directly linked to by the composition
   resource.
    In our case, we want any resources referred to by lists referenced from the composition
   to 
    be included as well. 
    
    We do this by defining a 'graph' of resources - and then we'll say to the $document
   server,
    aggregate this graph as well as other resources. So we define a graph that starts
   at composition,
    goes from section to list, and includes all the resources the list includes. 
    
    While we're at it, we're going to say that all these resources must be about the same
   patient.
    Note that there are use cases for crossing patient record boundaries in documents,
   but not *this case*.

  <!--    this graph starts with a composition. We don't care what the specific profile is
     (though the statement above 'this case doesn't cross patients' implies that we do
   care a little)    -->

      one target. This graph is not making rules about the content of the section entries

      would be done in a profile. it's just saying, if you see a reference to a list in
     a section
      entry, these are the rules that describe the graph
