That just "says" you're going to "use" DA key frames; you now have to supply some;
e.g.
</DoubleAnimationUsingKeyFrames>
<EasingDoubleKeyFrame Value="0" KeyTime="0:0:24">
<EasingDoubleKeyFrame.EasingFunction>
<ExponentialEase EasingMode="EaseInOut" />
</EasingDoubleKeyFrame.EasingFunction>
</EasingDoubleKeyFrame>
<DoubleAnimationUsingKeyFrames
Then you can think about "binding".
(I generate my key frames in code - since they usually follow a function)
