Is there a concrete example in the Cocoon samples 
(or the Wiki)  that "fleshes out" this approach in a little 
more detail?

Thanks
Derek

If you have an XML *string* that you want JXTemplate to output as XML,  
you need to parse the string and convert it to a DOM Document object.

You can use the Cocoon parser component from Flow to build a DOM, and  
pass it to JX in the sendPage arguments.

Happy ditching ;-)

Maybe not, but here are some code excerpts:

   import org.apache.excalibur.xml.dom.DOMParser;
   import org.w3c.dom.Document;
   import org.xml.sax.InputSource;

     ServiceManager manager;
    (obtained via Serviceable or something)

     public Document stringToDOM(String input) throws Exception {
         Document result = null;
         DOMParser parser = null;
         try {
             parser = (DOMParser)manager.lookup(DOMParser.ROLE);
             result = parser.parseDocument(new InputSource(new 
StringReader(input)));
         } finally {
             manager.release(parser);
         }
         return result;
     }

You could also do it directly from Flowscript by using 
cocoon.createComponent to do the lookup.
