RE: Processing empty nodes in XSLT

You need to re-educate the recipient of the XML that CDATA has no semantics.
If you can't do that, you need to write your own serializer.

Or perhaps you could output processing instructions <?start-cdata?> and
<?end-cdata?> and then postprocess the output to turn these into <![CDATA[
and ]]> respectively.
