Well, right now there is no registration process. That's one of the open 
issues we need to resolve (extensibility).

IMHO link relations need to be defined outside the scope of HTML -- they 
can be used with any type of resource after all. Thus I would prefer 
either an open extensibility model (URI based), or a independant 
registry such as IANA (or a combination of both).
