else

Provides the final alternative in an if construct.

Copy 
<if cond="ECMAScript_Expression">
   <!-- executable content -->
<elseif cond="ECMAScript_Expression"/>
   <!-- executable content -->
<elseif cond="ECMAScript_Expression"/>
   <!-- executable content -->
<else/>
   <!-- executable content -->
</if>

If the cond attributes of the containing if and preceding elseif elements evaluate to false, the content between the else element and the closing if tag is executed.

The following example request the name of a flower from the user, compares the value returned by the grammar, and plays back audio about the flower.
