Error when overriding mx_internal function in mxml file

Question

Hi,
I'm having difficulty overriding an mx_internal function inside an mxml file. I get an error:
1004: Namespace was not found or is not a compile-time constant. StackRenderer.mxml /Layouts/src/example line 12 Flex Problem
<?xml version="1.0" encoding="utf-8"?>
     <s:ItemRenderer
            xmlns:fx="http://ns.adobe.com/mxml/2009"
            xmlns:s="library://ns.adobe.com/flex/spark"
            xmlns:mx="library://ns.adobe.com/flex/mx">
            <fx:Script>
                  <![CDATA[
                        import mx.core.mx_internal;
                        use namespace mx_internal;
                        override mx_internal function drawBackground():void{
                   ]]>
            </fx:Script>
</s:ItemRenderer>
What am I doing wrong?

Sorry for missleading information: I missed the error after I removed "use namespace mx_internal;". However I think I have found a problem. For some reason you get the error in MXML file (probably there are some restrictions for using namespaces in MXML files but I'm not sure). I have created an ActionScript component and it now compiles (for sure):
package
   import mx.core.mx_internal;
   import spark.components.supportClasses.ItemRenderer;
   use namespace mx_internal
   public class CustomIRAS extends ItemRenderer
      override mx_internal function drawBackground():void {
So I suggest creating ActionScript component instead of MXML.
