The option Element - <option>

Description:
When a simple set of alternatives is all that is needed to specify the legal input values for a field, it may be more convenient to use an option list than a grammar. An option list is represented by a set of <option> elements contained in a <field> element. Each <option> element contains PCDATA that is used to generate a grammar for the spoken input it accepts using the same method described for <choice>. It also has attributes specifying the DTMF key for selecting the option and the value to assign to the field when the option is chosen.

Example:

<form>

  <field name="maincourse">

    <prompt>Please select an entree. Today, we�re featuring <enumerate/></prompt>

    <option dtmf="1" value="fish"> swordfish </option>

    <option dtmf="2" value="beef"> roast beef </option>

    <option dtmf="3" value="chicken"> frog legs </option>

    <filled>

      <submit next="/cgi-bin/maincourse.cgi" method="post" namelist="maincourse"/> 

    </filled>

  </field>

</form>

Attributes
