Plus, consider that a server returning the same content for both URIs 
above is a configuration choice, quite common now but perhaps not some 
time in the future (like when a security warning say that you have to 
reject every URI with query parameters on resources not handling them ;) )
So you can't even rely on a fallback mechanism to do discovery based on 
the structure of the URI.
