Let me clarify what I meant. You originally wrote:

[emphasis mine]

Should implementations be allowed or required to use intrinsic  
knowledge from other sources than media type registration? For  
example, suppose my user agent recognizes "image/svg-xml" or "text/ 
xsl". Should it then treat these as XML, even though they are  
unregistered, and will likely never be registered?

Registering types is of course a good idea, but unrelated to the  
point I was trying to make. I just wanted you to clarify whether you  
intended "knowledge derived from the media type registration" to  
limit this behavior solely to registered types.
