Accessing ListBox DisplayMemberPath data value in SelectedItem template

I am attempting to create a generic ListBox control to customize edit in place as well as other features.

In the example below, I want to bind the "Text" property of the ListBox "selected item" to the data value of the DisplayMemberPath in the viewed structure. Such XAML binding expression would replace the question marks in the code (Text="{Binding ????????????????").

Using a ContentPresenter instead of binding the text works for display purposes, but I have not been able to bind to the Text component used on the presenter. An alternative to finding the binding expression is to be able to get the Text content from the ContentPresenter.

I can think of a number of ways to accomplish this through code behind, but I am looking for a XAML solution if such thing exists.

I appreciate any ideas. I am almost sure there is a trivial answer to this, but after spending a couple days on it, I admit a nudge in the right direction would greatly help me.

<Grid>
    <ListBox Style="{DynamicResource TestListBoxStyle}"
             ItemsSource="{Binding Source={StaticResource NobelLaureatesInPhysics}, XPath=NobelLaureate}"
             DisplayMemberPath="Name"/>
</Grid>

{Binding Path=DisplayMemberPath, RelativeSource={RelativeSource Mode=FindAncestor, Type={x:Type ListBox}}

That should work
