Use XML child node as label in Spark list itemRenderer

Question

In ActionScript, I whittle down my XML to a series of nodes, all formed like this:

<option letter="A">
    <letter>A</letter>
    <response>Thank you</response>
    <posFeed>Excellent</posFeed>
    <negFeed>Terrible</negFeed>
    <score>-1</score>
    <elimOptions>B</elimOptions>
</option>

When I set this series as the dataProvider for my Spark list that uses a custom item renderer with a Spark label, I set the label.text={data}, which displays each full set of nodes as a list item.

If I don't want to whittle the XML down to just the nodes beforehand (I'd like the full set intact for other functions I have to perform), how can I set just the response node to be the data to use for the label in the itemRenderer? I tried setting the label text={data.response}, but that doesn't work (a full set of nodes still appears as each list item.

Like this:

<fx:Declarations>
    <fx:XML id="data">
        <options>
            <option letter="A">
                <letter>A</letter>
                <response>Thank you</response>
                <posFeed>Excellent</posFeed>
                <negFeed>Terrible</negFeed>
                <score>-1</score>
                <elimOptions>B</elimOptions>
            </option>
            <option letter="B">
                <letter>B</letter>
                <response>Thank you B</response>
                <posFeed>Excellent B</posFeed>
                <negFeed>Terrible B</negFeed>
                <score>-1</score>
                <elimOptions>B</elimOptions>
            </option>
        </options>
    </fx:XML>
</fx:Declarations>

<s:List labelField="response">
    <s:dataProvider>
        <s:XMLListCollection source="{data.option}" />
    </s:dataProvider>
</s:List>

I should add that when I did this, I didn't have any trouble using a custom item renderer:

<s:List itemRenderer="DataItemRenderer">
    <s:dataProvider>
        <s:XMLListCollection source="{data.option}" />
    </s:dataProvider>
</s:List>

<s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009" 
                xmlns:s="library://ns.adobe.com/flex/spark" 
                xmlns:mx="library://ns.adobe.com/flex/mx" 
                autoDrawBackground="true">

    <s:Label text="{data.response}"/>

</s:ItemRenderer>
