/**
 * Music CD identifier frame.
 * 
 * <p>
 * This frame is intended for music that comes from a CD, so that the CD
 * can be identified in databases such as the CDDB. The frame
 * consists of a binary dump of the Table Of Contents, TOC, from the CD,
 * which is a header of 4 bytes and then 8 bytes/track on the CD plus 8
 * bytes for the 'lead out' making a maximum of 804 bytes. The offset to
 * the beginning of every track on the CD should be described with a
 * four bytes absolute CD-frame address per track, and not with absolute
 * time. This frame requires a present and valid "TRCK" frame, even if
 * the CD's only got one track. There may only be one "MCDI" frame in
 * each tag.
 * </p><p><table border=0 width="70%">
 * <tr><td colspan=2> &lt;Header for 'Music CD identifier', ID: "MCDI"&gt;</td></tr>
 * <tr><td>CD TOC</td><td>&lt;binary data&gt;</td></tr>
 * </table></p>
 * 
 * <p>For more details, please refer to the ID3 specifications:
