/**
 * The 'jxta' ID Format is used for the presentation of a limited number of
 * well-known ids. These are the null id, the world peer group id, and the
 * default net peer group id. JXTA depends on being able to refer to these
 * standard entities in a common way regardless of what other id formats are
 * used, indeed this ID Format and these ids exist so that there are not a
 * different representations for the ids of these entities with each ID Format.
 *
 * <p/>Rather than return its own version of these well known IDs, each ID
 * Format <b>MUST</b> return these IDs as appropriate.
 *
 * <ul>
 * <li>the null id - the NullID is often used as a placeholder in fields which
 * are uninitialized.</li>
 *
 * <li>the world peer group id - the id of the world peer group.</li>
 *
 * <li>the default net peer group id - the id of the default net peer group.</li>
