I would say that this syntax from your email is easiest to use. As Mark
explained, the xml-type language is old, version 2.0. You can define a
domain specific language, but that's worth the effort only in larger
projects, I'd say.

rule "Hello World"

   when
        m : Message( status == Message.HELLO, message : message)
   then
        System.out.println( message );
        modify ( m ) { message = "Goodbyte cruel world",
        status = Message.GOODBYE };
        System.out.println( message );
end
