It all depends on real world app. Yes, XML contains valueable info that CSV doesn't (at least not directly). But back to this case, CSV is sufficient. It is just like that you do not need to deploy JBOSS to write a simple guest book by using complex Java EE patterns. PHP can do that very decently with much less work.
