XML Connector with Radio Buttons?

Can I use the XML Connector for Radio Buttons?

I have an XML file structured like this:


<vehicle>
     <new>
          <make MakeName="Buick">
               <model>LeSabre</model>
          </make>
     </new>
     <used>
          <make MakeName="Buick">
               <model>LeSabre</model>
          </make>
     </used>
</vehicle>

I’m using the XML Connector component, and I’ve successfully used both a combobox and a text field, but I can’t even select the radio button inside the Bindings field.

Can I use Radio Buttons with the XML Connector? Can I use XML at all with radio buttons?

Thanks!
