Packed Encoding Rules

   <protocol, standard> (PER) {ASN.1} encoding rules for
   producing a compact {transfer syntax} for data structures
   described in {ASN.1}, defined in 1994.

   PER provides a much more compact encoding then {BER}.  It
   tries to represents the data units using the minimum number of
   {bits}.  The compactness requires that the decoder knows the
   complete {abstract syntax} of the data structure to be
   decoded, however.

   Documents: {ITU-T} X.691, {ISO} 8825-2.
