         Parameter Type is a one octet field that unambiguously
         identifies individual parameters.  Parameter Length is a one
         octet field that contains the length of the Parameter Value
         field in octets.  Parameter Value is a variable length field
         that is interpreted according to the value of the Parameter
         Type field.
