Can I use XAML to set a nested property (property value property) of a control?

Question

I have a WPF control that exposes one of its children (from it a ControlTemplate) through a read-only property. At the moment this is just a CLR property, but I don't think it matters.

I want to be able to set one of the properties of a child control from XAML, where I create the main control. (Actually, I would like to get attached to it, but I think setting this up would be a good first step.)

Here is the code:

public class ChartControl : Control
{
    public IAxis XAxis { get; private set; }

    public override void OnApplyTemplate()
    {
        base.OnApplyTemplate();

        this.XAxis = GetTemplateChild("PART_XAxis") as IAxis;
    }
}

public interface IAxis
{
    // This is the property I want to set
    double Maximum { get; set; }
}

public class Axis : FrameworkElement, IAxis
{
    public static readonly DependencyProperty MaximumProperty = DependencyProperty.Register("Maximum", typeof(double), typeof(Axis), new FrameworkPropertyMetadata(20.0, FrameworkPropertyMetadataOptions.AffectsRender, OnAxisPropertyChanged));

    public double Maximum
    {
        get { return (double)GetValue(MaximumProperty); }
        set { SetValue(MaximumProperty, value); }
    }
}

Here are two ways I can imagine to set a nested property in XAML (nor compile):

<!-- 
    This doesn't work:
    "The property 'XAxis.Maximum' does not exist in XML namespace 'http://schemas.microsoft.com/winfx/2006/xaml/presentation'."
    "The attachable property 'Maximum' was not found in type 'XAxis'."
-->
<local:ChartControl XAxis.Maximum="{Binding Maximum}"/>

<!-- 
    This doesn't work: 
    "Cannot set properties on property elements."
-->
<local:ChartControl>
    <local:ChartControl.XAxis Maximum="{Binding Maximum}"/>
</local:ChartControl>

Is it possible?
