DESCRIPTION

       Get  the  PSKC  KeyPackage  Key  AlgorithmParameters  ResponseFormat  CheckDigits  value.  This attribute
       indicates whether the device needs to append a Luhn check digit,  as  defined  in  [ISOIEC7812],  to  the
       response.   This  is  only  valid if the 'Encoding' attribute is set to 'DECIMAL'.  If the value is TRUE,
       then the device will append a Luhn check digit to the response.  If the value is FALSE, then  the  device
       will not append a Luhn check digit to the response.

       If present is non-NULL, it will be 0 if the field is not present or 1 if it was present.

RETURNS

       1 to indicate a CheckDigits value of true, or 0 to indicate false.
