We could come up with attributes of different media types and make 
them separate Accept: parameters all day, but I don't think that would 
get us very far.  Instead let's roll this in with the 406 response - the 
color attrributes, or any arbitrary media-specific attributes, are just 
more metadata that the browser could use to make its object 
selection decision.  I.e., the 406 response back for "http://host/image" 
could look like

URI: http://host/image.gif8c
Content-type: image/gif; bitdepth=8-color

URI: http://host/image.gif8g
Content-type: image/gif; bitdepth=8-gray

URI: http://host/image.jpg
Content-type: image/jpeg

URI: http://host/image.tiff
Content-type: image/tiff; bitdepth=24-color

Or something like that.  It looks like the "color" or "bitdepth" or any 
attribute is going to be at least mime-major-type specific, perhaps 
subtype-specific too.
