   The  rule describes the GSER encoding of values of the
   INTEGER type without a named number list.  The  rule
   describes the GSER encoding of values of the constrained type INTEGER
   (0..MAX).  The  rule describes the GSER encoding of
   values of the constrained type INTEGER (1..MAX).

      INTEGER         = "0" / positive-number / ("-" positive-number)
      INTEGER-0-MAX   = "0" / positive-number
      INTEGER-1-MAX   = positive-number
      positive-number = non-zero-digit *decimal-digit
      decimal-digit   = %x30-39  ; "0" to "9"
      non-zero-digit  = %x31-39  ; "1" to "9"

   The  rule describes the GSER encoding of values of the
   associated type for the EMBEDDED PDV type.

      EMBEDDED-PDV = "{" sp id-identification msp Identification ","
                         sp id-data-value msp OCTET-STRING
                         sp "}"

   The  rule describes the GSER encoding of values of the
   associated type for the EXTERNAL type.
