如何将HeaderTemplateProperty应用于CustomControl中的HeaderProperty？

public class CustomControl : Control
{
    public static readonly DependencyProperty HeaderTemplateProperty =
        DependencyProperty.Register("HeaderTemplate", typeof(ControlTemplate), typeof(CustomControl), new PropertyMetadata(null));

    public static readonly DependencyProperty HeaderProperty =
        DependencyProperty.Register("Header", typeof(object), typeof(CustomControl), new PropertyMetadata(null));

    public ControlTemplate HeaderTemplate
    {
        get { return (ControlTemplate)GetValue(HeaderTemplateProperty); }
        set { SetValue(HeaderTemplateProperty, value); }
    }

    public object Header
    {
        get { return GetValue(HeaderProperty); }
        set { SetValue(HeaderProperty, value); }
    }

    static CustomControl()
    {
        DefaultStyleKeyProperty.OverrideMetadata(typeof(CustomControl), new FrameworkPropertyMetadata(typeof(CustomControl)));
    }

    protected virtual void OnHeaderTemplatePropertyChanged(ControlTemplate oldTemplate, ControlTemplate newTemplate)
    {
        // 更新头部模板的逻辑
    }
}
