Многократное использование DataTemplate

У меня есть два DataTemplates для различных ячеек в моем управлении Treelistview. шаблоны на 90% подобны. Как я могу снова использовать идентичный Xaml?

  <DataTemplate x:Key="@names">
            <TextBlock Name="txt" Text="{Binding Names}" Style="{DynamicResource @BasicTextBlockStyle}"
                    Foreground="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Border},AncestorLevel=1}, Path=BorderBrush,Mode=OneWay}" />
            <DataTemplate.Triggers>
                <DataTrigger Binding="{Binding IsVisible}" Value="True">
                    <Setter Property="Style" Value="{DynamicResource @HeaderTextBlockStyle}" TargetName="txt" />
                </DataTrigger>
                <DataTrigger Binding="{Binding IsScoped}" Value="True">
                    <Setter Property="Style" Value="{DynamicResource @RootElementTextBlockStyle}" TargetName="txt" />
                </DataTrigger>
            </DataTemplate.Triggers>
        </DataTemplate>

        <DataTemplate x:Key="@Ages">
            <TextBlock Name="txt" Text="{Binding Age}" Style="{DynamicResource @BasicTextBlockStyle}"
                    Foreground="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Border},AncestorLevel=1}, Path=BorderBrush,Mode=OneWay}" />
            <DataTemplate.Triggers>
                <DataTrigger Binding="{Binding IsVisible}" Value="True">
                    <Setter Property="Style" Value="{DynamicResource @HeaderTextBlockStyle}" TargetName="txt" />
                </DataTrigger>
                <DataTrigger Binding="{Binding IsScoped}" Value="True">
                    <Setter Property="Style" Value="{DynamicResource @RootElementTextBlockStyle}" TargetName="txt" />
                </DataTrigger>
            </DataTemplate.Triggers>
        </DataTemplate>
