XMLOutput uses aggregation to work with any SAX ContentHandler or
LexicalHandler so no need to derive.
XMLParser is a ContentHandler and LexicalHandler. So you could do 
something
like this in pseudo code

public class EvalTag extends TagSupport {
    private String var;
    public void doTag(XMLOutput output) throws JellyTagException {
        XMLParser parser = new XMLParser();
        XMLOutput newOutput = new XMLOutput( parser );
        // invoke body, redirecting SAX events into the Jelly parser
        invokeBody( newOutput );
        Script script = parser.getScript();
        if (var != null) {
            context.setVariable(var, script);
        }
        else {
            // lets just execute the new script
            script.run(context, output);
        }
    }
}

Pretty much exactly what I'd done with my previous message, though I'm 
still having an issue with variables set in the body's script not being 
visible to the parent script.

Ideas?
