### Example

```markup
<?xml version="1.0"?>
<vxml version="2.0">
  <form id="start">
    <field name="dt">
      <grammar root="main" type="application/srgs+xml" mode="voice">
        <rule id="main" scope="public">
          <item>
            <ruleref uri="#month"/>
            <ruleref uri="#day"/>
          </item>
          <tag> month = month.SWI_literal; day = day.SWI_literal; </tag>
        </rule>
      
        <rule id="month">
          <one-of>
            <item>May</item>
            <item>June</item>
            <item>October</item>
          </one-of>
        </rule>
      
        <rule id="day">
          <one-of>
            <item>first</item>
            <item>second</item>
            <item>third</item>
          </one-of>
        </rule>      
      </grammar>
      
      <prompt>Please say a date.</prompt>
      
      <filled>
        <prompt bargein="false">
          I think you said month <value expr="dt.month"/> 
          day <value expr="dt.day"/>.
        </prompt>
      </filled>
      
      <nomatch>
        I'm sorry, I didn't catch that.
        <reprompt/>
      </nomatch>
    </field>
  </form>
</vxml>
```

The output of the above script would be:

> Computer: Please say a date.\
> Human: June second.\
> Computer: I think you said month June day second.
