The `Pairwise` tag is used to compare two different objects and select one item from the list. If you want annotators to compare two objects and determine whether they are similar or not, use the `Choices` tag.

Use with the following data types: audio, image, HTML, paragraphs, text, time series, video.
@example
<!--Basic labeling configuration to compare two passages of text -->
<View>
  <Header value="Select the more accurate summary"/>
  <Pairwise name="pairwise" leftClass="text1" rightClass="text2" toName="txt-1,txt-2"></Pairwise>
  <Text name="txt-1" value="Text 1" />
  <Text name="txt-2" value="Text 2" />
</View>
@example
<!-- You can also style the appearance using the View tag: -->
<View>
  <Pairwise name="pw" toName="txt-1,txt-2"></Pairwise>
  <View style="display: flex;">
    <View style="margin-right: 1em;"><Text name="txt-1" value="$text1" /></View>
    <View><Text name="txt-2" value="$text2" /></View>
  </View>
</View>
