The latter is more what I am concerned about, since people make up rel  
values all the time without asking anyone's permission.

No one said it did.

I don't think it's a good idea to leave values in common use  
completely undocumented in the registry. It means that a good  
samaritan who finds someone else's unregistered header cannot ensure  
that it is documented without writing a full specification that will  
survive formal review.

Like I said, I'm not going to object on this basis, I was just curious  
to hear from Mark why there is not any form of provisional or  
experimental registration.
