I've encountered a problem where a ConditionalAttribute on my Chart works fine when the Chart is defined in the normal body of the Xaml.  The ConditionalAttributes are completely ignored when used on a Chart defined in a DataTemplate though.  Working and non-working examples are shown below, and suggestions would be appreciated.

<Window x:Class="ChartFXSandbox.Window1"

  <Window.Resources>
    <XmlDataProvider x:Key="ChartData" XPath="/Coordinates/Coordinate">
      <x:XData>
        <Coordinates xmlns="">
          <Coordinate>
            <Domain>1</Domain>
            <Range>2</Range>
          </Coordinate>
          <Coordinate>

            <Range>10</Range>
          </Coordinate>
        </Coordinates>
      </x:XData>
    </XmlDataProvider>

    <DataTemplate x:Key="ChartDataTemplate" DataType="ChartData">
      <cfx:Chart ItemsSource="{Binding Source={StaticResource ChartData}}" Gallery="Line">

            </cfx:ConditionalAttributes.Condition>
          </cfx:ConditionalAttributes>
        </cfx:Chart.ConditionalAttributes>     
      </cfx:Chart>
    </DataTemplate>
   
  </Window.Resources>

            </cfx:ConditionalAttributes.Condition>
          </cfx:ConditionalAttributes>
        </cfx:Chart.ConditionalAttributes>
      </cfx:Chart>
