如何使用带有自定义路由事件的用户控件在caliburn micro中传递参数？

public class CustomControl : UserControl
{
    public static readonly RoutedEvent CustomEvent = EventManager.RegisterRoutedEvent(
        "Custom", RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(CustomControl));

    public event RoutedEventHandler Custom
    {
        add { AddHandler(CustomEvent, value); }
        remove { RemoveHandler(CustomEvent, value); }
    }

    // 其他控件逻辑...
}

<local:CustomControl>
    <local:CustomControl.Triggers>
        <EventTrigger RoutedEvent="local:CustomControl.Custom">
            <cal:ActionMessage MethodName="HandleCustomEvent">
                <cal:Parameter Value="参数值" />
            </cal:ActionMessage>
        </EventTrigger>
    </local:CustomControl.Triggers>
</local:CustomControl>

public void HandleCustomEvent(string parameter)
{
    // 处理传递的参数...
}
