Shouldn't the mimetype be **application/rdf+xml**, that's what the RELS-EXT uses as it is RDF, and what is recommend [IETF](http://www.ietf.org/rfc/rfc3870.txt). Or does the TEI-RDF datastream no longer contain RDF? As the Sample Objects have had that removed recently, are we sure their will be no RDF in the TEI? If so then this would be correct as the TEI organization has not registered **application/tei+xml**. If that is the case, we should probably rename the object and it's datastream such that it no longer references RDF to be clear.
