/** process instance for which the relations are exposed.  
 * 
 * Open refers to the relations being accessible.  This is related 
 * to hibernate's lazy loading capabilities.  That requires an active 
 * session.  Inside process execution, there is such an active session
 * and hence the relations can be exposed.  But for the client of the 
 * service methods, it's not sure if the session is still active.  
 * That is why the relations are not exposed in the return values 
 * of service methods.
