    * Note that synthetic mouse events will be generated from touch events if
    * (and only if) the you do not request touch events.
    *
    * When requesting input events through this function, the events will be
    * delivered and <i>not</i> bubbled to the page. This means that even if you
    * aren't interested in the message, no other parts of the page will get
    * a crack at the message.
    *
    * <strong>Example:</strong>
-   * <code>
+   * @code
    *   RequestInputEvents(instance, PP_INPUTEVENT_CLASS_MOUSE);
    *   RequestFilteringInputEvents(instance,
    *       PP_INPUTEVENT_CLASS_WHEEL | PP_INPUTEVENT_CLASS_KEYBOARD);

    * @param instance The <code>PP_Instance</code> of the instance requesting

    * <code>PP_InputEvent_Class</code> that identifies the classes of events the
    * instance is requesting. The flags are combined by logically ORing their
    * values.

    * Filtering input events requires significantly more overhead than just
    * delivering them to the instance. As such, you should only request
    * filtering in those cases where it's absolutely necessary. The reason is
    * that it requires the browser to stop and block for the instance to handle
    * the input event, rather than sending the input event asynchronously. This
    * can have significant overhead.

    * <strong>Example:</strong>
-   * <code>
+   * @code
    *   RequestInputEvents(instance, PP_INPUTEVENT_CLASS_MOUSE);
    *   RequestFilteringInputEvents(instance,

    * <code>PP_ERROR_NOTSUPPORTED</code> if one of the event class bits were
    * illegal. In the case of an invalid bit, all valid bits will be applied
    * and only the illegal bits will be ignored.
