/**
 * A {@code SysexMessage} object represents a MIDI system exclusive message.
 * <p>
 * When a system exclusive message is read from a MIDI file, it always has a
 * defined length. Data from a system exclusive message from a MIDI file should
 * be stored in the data array of a {@code SysexMessage} as follows: the system
 * exclusive message status byte (0xF0 or 0xF7), all message data bytes, and
 * finally the end-of-exclusive flag (0xF7). The length reported by the
 * {@code SysexMessage} object is therefore the length of the system exclusive
 * data plus two: one byte for the status byte and one for the end-of-exclusive
 * flag.
 * <p>
 * As dictated by the Standard MIDI Files specification, two status byte values
 * are legal for a {@code SysexMessage} read from a MIDI file:
 * <ul>
 *   <li>0xF0: System Exclusive message (same as in MIDI wire protocol)
 *   <li>0xF7: Special System Exclusive message
 * </ul>
 * When Java Sound is used to handle system exclusive data that is being
 * received using MIDI wire protocol, it should place the data in one or more
 * {@code SysexMessages}. In this case, the length of the system exclusive data
 * is not known in advance; the end of the system exclusive data is marked by an
 * end-of-exclusive flag (0xF7) in the MIDI wire byte stream.
 * <ul>
 *   <li>0xF0: System Exclusive message (same as in MIDI wire protocol)
 *   <li>0xF7: End of Exclusive (EOX)
 * </ul>
 * The first {@code SysexMessage} object containing data for a particular system
 * exclusive message should have the status value 0xF0. If this message contains
 * all the system exclusive data for the message, it should end with the status
 * byte 0xF7 (EOX). Otherwise, additional system exclusive data should be sent
 * in one or more {@code SysexMessages} with a status value of 0xF7. The
 * {@code SysexMessage} containing the last of the data for the system exclusive
 * message should end with the value 0xF7 (EOX) to mark the end of the system
 * exclusive message.
 * <p>
 * If system exclusive data from {@code SysexMessages} objects is being
 * transmitted using MIDI wire protocol, only the initial 0xF0 status byte, the
 * system exclusive data itself, and the final 0xF7 (EOX) byte should be
 * propagated; any 0xF7 status bytes used to indicate that a
 * {@code SysexMessage} contains continuing system exclusive data should not be
 * propagated via MIDI wire protocol.
