+        <p>The maximum length in characters for any individual status
+          message, or 0 if there is no limit.</p>
+
+        <p>While the connection is in the DISCONNECTED state, this property will
+          be 0. The connection manager will attempt to set the appropriate value
+          when the connection becomes connected, but cannot necessarily
+          guarantee it. The maximum length cannot change until the
+          connection status changes, so there is no change notification.</p>
+
+        <p>While the connection is in the CONNECTED state, this property
+          contains the maximum length in characters for any individual status
+          message which is actually allowed on this protocol.
+          This value is constant for the remaining lifetime
+          of the connection, so again, there is no change notification.</p>
+
+        <p>While the connection is in the CONNECTING state, the value of
+          this property is undefined and SHOULD NOT be used. It can change
+          at any time without notification (in particular, any cached values
+          from when the connection was in the DISCONNECTED or CONNECTING
+          state MUST NOT be assumed to still be correct when the state has
+          become CONNECTED).</p>
+
+        <p>The connection manager MUST truncate the status message being set if
+          its length is bigger than the value of this property and
+          PresencesChanged MUST be emitted properly with the truncated
+          status message.</p>
+
+        <tp:rationale>
+          <p>Some XMPP servers, like Google Talk, define a maximum length for
+          status messages. Whether the user's server is one of
+          these cannot be detected until quite late in the connection
+          process.</p>
