I understand that some people want to introduce a media type for 
each XML vocabulary.  Nevertheless, I have also heard a lot of 
questions about such specialized media types.  First, specialized 
media types do not help multi-namespace XML documents.  Second, if 
fine-grained dispatching or content negotiation rely on media types only, 
we will eventually need even finer media types such as 
application/rng-ASCIINamesOnly+xml.  

In the case of XSLT, we still do not have any specialized media types.

In the case of iCalendar, a specilized media type was created, since
people want to retrieve MIME headers and then retrieve XML only when 
necessary.

I am still not convineced if application/relaxng+xml is needed.  But 
if many people have good reasons to introduce it, I will not argue 
against it.
