    043 * Extension that adds better handling of extra fields and provides access to the internal and external file attributes.

    047 * </p>
    048 * <ul>
    049 * <li>the extra byte array consists of a sequence of extra fields</li>
    050 * <li>each extra fields starts by a two byte header id followed by a two byte sequence holding the length of the remainder of data.</li>
    051 * </ul>
    052 *
    053 * <p>
    054 * 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.
    055 * 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
    056 * recommendation.
