I presume that you want the data inside the CDATA block for the sake
of the client? Since printing out the data would create a text node
for the internal processing and wouldn't be touched by Cocoon at all.

I think it should be possible to print the CDATA instruction
("&lt;![CDATA[") and the ending instruction ("]]&gt;").

Effectively escapes the esql-tag from being replaced by the required
java code.

Mmmh, that _should_ work. Could you please provide us with the java
code produced by this? You'll find it in the work directory of your
servlet engine (e.g. $CATALINA_HOME/work/localhost/cocoon/....)

Wait -- that sounds like a correct result. What are you trying to
achieve exactly?
