  <Switch>
    <Case test=" $counter &lt; 5">
      <SetVariable variable="text" select="'Less than 5'"/>
    </Case>
    <Case test=" $counter &lt; 20">
      <SetVariable variable="text" select="'Less than 20'"/>
    </Case>
    <Otherwise>
      <SetVariable variable="text" select="'Larger or equal to 20'"/>
    </Otherwise>
  </Switch>
  <PlaceObject>
    <Textblock>
      <Paragraph><Value select="$text"/></Paragraph>
    </Textblock>
  </PlaceObject>
</Record>

Info

You have to be careful to encode the test with the rules of XML: that is »less« must be written as &lt;, since < must not be part of text contents.

A Switch may be part of nearly all commands. It dissolves and only the contents of the Case or Otherwise gets replaced by the whole construct.
