- the extra byte array consists of a sequence of extra fields
- each extra fields starts by a two byte header id followed by a two byte sequence holding the length of the remainder of data.
Any extra data that cannot be parsed by the rules above will be consumed as "unparseable" extra data and treated differently by the methods of this class. Versions prior to Apache Commons Compress 1.1 would have thrown an exception if any attempt was made to read or write extra data not conforming to the recommendation.
