Problem with CDATA

Hi all,

I have a XSLT file which insert script node into a source SVG file and create the result SVG file with script node in it.

I hardcoded following code:

<script type="text/ecmascript"><[CDATA[
    AA
 ]]> </script>


What I got into the result SVG file is like this:

<script type="text/ecmascript">
  AA
</script>


It seems <[CDATA[  ]]> is not copied into destination documents. 
But the result SVG file will have a bug without <[CDATA[  ]]> inside of script node.
How can I put the "<[CDATA[  ]]>" into the result file?

Can anybody help me?
