Registered means that the string is registered with a registry.

That's not something I'd want the language to even hint at, let alone  
actually say. It's going to lead to confusion when explaining this to  
people, as you'll need to directly contradict the wording in the spec  
when you reassure them that, no, there is no central DKIM registry.
