- * <li>{@link #ERROR}</li>
- * <li>{@link #WARN}</li>
- * <li>{@link #INFO}</li>

+ * <td>{@link #OFF}</td>

* Typically, configuring a level in a filter or on a logger will cause
logging events of that level and those that are
* more specific to pass through the filter. A special level, {@link #ALL}, is
guaranteed to capture all levels when
* used in logging configurations.
