 *
 * <td>An indication that this element of the information model is no
 * longer recommended for use.  A set of MBeans defined by an
 * application is collectively called an <em>information model</em>.
 * The convention is for the value of this field to contain a string
 * that is the version of the model in which the element was first
 * deprecated, followed by a space, followed by an explanation of the
 * deprecation, for example {@code "1.3 Replaced by the Capacity
 * attribute"}.</td>

 * <td>The base name for the {@link ResourceBundle} in which the key given in

 * {@code "com.example.myapp.MBeanResources"}.  The meaning of this
 * field is defined by this specification but the field is not set or
 * used by the JMX API itself.</td>
 *
 * <tr><td>descriptionResourceKey</td><td>String</td><td>Any</td>
 *
 * <td>A resource key for the description of this element.  In
 * conjunction with the {@code descriptionResourceBundleBaseName},

 *
 * <td>The string {@code "true"} or {@code "false"} according as this
 * item is enabled.  When an attribute or operation is not enabled, it
 * exists but cannot currently be accessed.  A user interface might
 * present it as a greyed-out item.  For example, an attribute might
 * only be meaningful after the {@code start()} method of an MBean has
 * been called, and is otherwise disabled.  Likewise, a notification
 * might be disabled if it cannot currently be emitted but could be in
 * other circumstances.</td>

 * <td>MBeanInfo</td>
 *
 * <td>The string {@code "true"} or {@code "false"} according as this
 * MBean's MBeanInfo is <em>immutable</em>.  When this field is true,
 * the MBeanInfo for the given MBean is guaranteed not to change over
 * the lifetime of the MBean.  Hence, a client can read it once and
 * cache the read value.  When this field is false or absent, there is
 * no such guarantee, although that does not mean that the MBeanInfo
 * will necessarily change.</td>
 *
 * <tr><td>infoTimeout</td><td>String<br>Long</td><td>MBeanInfo</td>
 *
 * <td>The time in milli-seconds that the MBeanInfo can reasonably be
 * expected to be unchanged.  The value can be a {@code Long} or a
 * decimal string.  This provides a hint from a DynamicMBean or any
 * MBean that does not define {@code immutableInfo} as {@code true}
 * that the MBeanInfo is not likely to change within this period and
 * therefore can be cached.  When this field is missing or has the
 * value zero, it is not recommended to cache the MBeanInfo unless it
 * has the {@code immutableInfo} set to {@code true}.</td></tr>

 * <td>The type of a metric, one of the strings "counter" or "gauge".
 * A metric is a measurement exported by an MBean, usually an
 * attribute but sometimes the result of an operation.  A metric that
 * is a <em>counter</em> has a value that never decreases except by
 * being reset to a starting value.  Counter metrics are almost always
 * non-negative integers.  An example might be the number of requests
 * received.  A metric that is a <em>gauge</em> has a numeric value
 * that can increase or decrease.  Examples might be the number of
 * open connections or a cache hit rate or a temperature reading.
