An document with <xbl xmlns="http://.../xbl"> as its root element will 
already provide that functionality much more reliably than the MIME 
type.  It's the namespace that matters in XML, not the MIME type.

Another reason would be to allow for content negotiation, but that would 
only be useful if there were ever another binding language for browsers 
to choose from and authors had a reason to provide equivalent bindings 
in two different languages.
