media types are often sent completely wrong, especially with RDF, a 
quick scutter of /user generated/ linked data (for instance peoples foaf 
files) quickly shows up more incorrect and entirely made up media types 
than one would think is possible. Coupled with your own comments, I'd 
quickly suggest this is a non starter.

Agreed. The data publishing specialists can incorporate any wondrous 
arrangement we can conceive, it's the guys who want to publish a foaf 
profile on their personal site or stick a cc snippet on page that need 
considered strongly here.

if you consider the dereferencing process as being a black-box, then you 
don't see anything but the content; which is arguably often the case.
