title: Error 2062: no mapping between entity set and association set
body: <p>Are entities required to be mapped to a table or can they map to a stored procedure?</p>
  
  <p>I have an entity that does not map to any specific table, instead it maps to a stored procedure. </p>
  
  <p>I am getting the following error:</p>
  
  <blockquote>
    <p>Schema specified is not valid. Errors:
    Model.msl(6,6) : error 2062: No
    mapping specified for instances of the
    EntitySet and AssociationSet in the
