Comment 4 for bug 168405

Could the script attribute be handled as a special case?

Perhaps any elements could automatically add "<![CDATA[" and "]]>" when it is saved:

<script type="text/ecmascript" id="script2259">...</script>

automatically saved as:

<script type="text/ecmascript" id="script2259">
<![CDATA[
...
]]>
</script>

(If nothing else, it will reduce the size of the saved file.)
