If the application follows Postel's law and treats incoming messages  
(requests) differently from outgoing messages (responses), does this  
need to be reflected in the description languages? Is something as  
strict as XSD a good choice to describe what you send while something  
more flexible such as Schematron is better to describe what you'll  
accept?
