No.

A representation of X in the architecture is a digital encoding of the  
content of X.
  A horse doesn't have information content.

I think you would say "There can be many documents associated with a  
horse: you may have a picture of the horse, a text description of the  
horse, etc."

Content Negotiation is ONLY for different encodings/languages/versions  
of the same information.
