Validator conneg problem ?

report=It seems the validator makes no content negotiation.
The following URI accepts both text/html and application/rdf xml:
http://coldb.mnhn.fr/catalognumber/mnhn/p/p00084058

The validator probably does not specifies the 'Accept' header, it seems 
to fetch the HTML version (or perhaps is it a redirection support 
problem ?).
