       Set  the  PSKC  KeyPackage  Key  AlgorithmParameters  ChallengeFormat  CheckDigits value.  This attribute
       indicates whether a device needs to check the appended Luhn check  digit,  as  defined  in  [ISOIEC7812],
       contained  in  a challenge.  This is only valid if the 'Encoding' attribute is set to 'DECIMAL'.  A value
       of TRUE indicates that the device will check the appended Luhn check digit in a  provided  challenge.   A
       value of FALSE indicates that the device will not check the appended Luhn check digit in the challenge.
