isn't it better to do this in IE:
window.execScript(theActualScriptContent);
and in FF and other this:
window.eval(theActualScriptContent);

Ok here is my idea regarding sript src="....
I would transform that on the server side to a small javascript ala
var scriptTag = document.createElement("script");
scriptTag.src="<src>"; document.body.append(scriptTag);
since the eval is executed after the rendering is done, this should be
even safe on IE6!
That also would still mean that the update CDATA block is just
javascript only without any preprocessing which then can be pushed
straight into the eval function!
