You use a MIME type that is specific enough to ask for the encoding of the 
description that you want.

I'm still confused... supposing that for a particular resource my server 
supports the following representations

HTML
PDF
RDF+XML
RDF+N3

You seem to be saying that it's OK to use conneg to ask for the first 
two of these... but it's not OK to use it to request the other two?

Supposing also that my server supports a 'complex object' representation - 
for example, a METS package that contains both the HTML and the RDF+XML 
representation?

Am I allowed to use conneg to request that representation or not?
