 * The <code>Media</code> printing attribute specifies which

 * {@link javax.print.attribute.standard.MediaName} and

 * {@link javax.print.attribute.standard.MediaSizeName}:

 * <ul>

 * <li>Selection by paper source - selection of printer tray to be used.</li>

 * <li>Selection by name - e.g. A4 paper.</li>

 * <li>Selection by standard sizes - e.g. ISO A5, JIS B4.</li>

 * </ul>

 * Each of the sublcasses represents the IPP attribute <code>media</code>

 * and provides predefined values to be used.

 * <b>IPP Compatibility:</b> Media is an IPP 1.1 attribute.
