The data strings of this Packed Object areencoded in the order indicated by the Object Info section of the Packed Object,compacted exactly as described in Annex D of [ISO15962] (Encoding rules for No-Directory Access-Method), with the following two exceptions:The Object-Identifier is not encoded in the “No-Directory Data section”, because ithas already been encoded into the Object Info and Secondary ID sections.The Precursor is modified in that only the three Compaction Type Code bits aresignificant, and the other bits in the Precursor are set to ‘0’.Therefore, each of the data strings invoked by the ID Table entry are separately encodedin a modified data set structure as: The are determined and encoded as described in D.1.1 andD.1.2 of [ISO15962] and the is determined and encoded asdescribed in D.2 of [ISO15962].Following the last data set, a terminating precursor value of zero shall not be encoded(the decoding system recognizes the end of the data using the encoded ObjectLength ofthe Packed Object).I.7.2 Support for the Packed-Object compaction methodIf the Packed-Object compaction method was selected by the Compact-Parameter bits,then the Compact-Parameter bits are followed by zero or more Aux Format bits, as maybe invoked by the ID Table entries used in this Packed Object.
