  // 9/06/2012 nwright commented this out as the contract DOES specify that you can have 2 entries with the same key
  // This was a deliberate change from how R1 Dynamic Attributes worked at the request of an implementing institution 
  // The design change was to allow dynamic attributes could implement a list of values more naturally by repeating keys
  //
  // Also constraints defined here as annotations have no effect except on unit tests because this 
  // constraint does not exist in the schemas created by DBAs and generated via IMPEX
  // this would make the unit tests be out of sync with the actual implementation
