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