Allow convert element with string body and attributes

I found a thread about "convert element with string body and attributes" in user mail list(http://article.gmane.org/gmane.comp.java.xstream.user/2349), but it seems that no one fire an issue here.

I have a class like this:
class Dely {
public String code;
public String content;
}

I use it like this:
public static void main(String ...strings) {
XStream xstream = new XStream();
xstream.alias("dely", Dely.class);
xstream.useAttributeFor("code", String.class);

//xstream.setDefaultContent("content", Dely.class);

Dely d = new Dely();
d.code = "abc";
d.content = "Hello";

System.out.println(xstream.toXML(d));
}

I would like the output xml as following:
<dely code="abc">Hello</dely>
