[flexcoders] mxml component and cdata block

[markgoldin_2000]

I am creating an mxml component based on TabNavigator:
?xml version="1.0" encoding="utf-8"?>   
<mx:TabNavigator xmlns:mx="http://www.adobe.com/2006/mxml";      
        x="5" y="0" width="99%" height="99%" backgroundColor="#DDE1B6">
.....
How can I add 
<mx:Script>
        <![CDATA[
        ]]>
    </mx:Script>

to it?

Thanks
