I'm very disappointed that in spite of your entire rewrite of the component it still does not fit well into the WPF eco system. Properties like DockingWindow.Title or DocumentWindow.Description are still of type String which counterworks the content driven idea of WPF.
Imagine where WPF would be today when FrameworkElement.ToolTip and HeaderedContentControl.Header would have been of type String. Right, no one would use, know or even remember WPF today.
