Silverlight 4.0 - How To Find A Silvlerlight Object On Page Using Microsoft UI Automation Testing

I have an object on my asp.net page hosting a Silverlight xap (in my particular case it is in an IFrame, but I'm curious about regular objects as well). I can find the element in UI Spy, but the name just says "Silverlight Control". Trying to find that AutomationElement in my automated test is unsuccessful (control is null every time). Is there a setting in the Silverlight code or in the html that would help? How can I distinguish it if there are multiple Silverlight controls on the same page?

<object id="silverlightClient" style="display:none;" data="data:application/x-silverlight-2," type="application/x-silverlight-2">
<param name="source" value="../../ClientBin/SilverlightApplication.xap"/>
<param name="onerror" value="onSilverlightError" />
<param name="background" value="#00000000" />
<param name="minRuntimeVersion" value="4.0.41019.0" />
<param name="autoUpgrade" value="true" />
<param name="windowless" value="false" />
</object>
TreeWalker tw = new TreeWalker(new System.Windows.Automation.PropertyCondition(AutomationElement.NameProperty, "Silverlight Control));
AutomationElement control = tw.GetFirstChild(ancestor);
