I continue to wonder what I'm missing here. Is this a requirement of media  
type registrations? If so, do you have a pointer?

Furthermore, if this is a requirement, why are references from a  
non-normative section sufficient?

Apart from this whether this is or is not a requirement, what is useful  
about this being defined in HTML5 if it has absolutely no effect on anyone  
whatsoever?


How does this work for other media type registrations? E.g. RFC 3023 only  
references the Second Edition of XML 1.0. Does that mean it cannot be used  
when namespaces are used in XML? Can it not be used for the Fifth Edition?  
The First? How does this work?
