Well, one of the priomary reasons for errata in general is 
to clarify what could be multiple interpretations of the same 
text in a specification. 

Any implementation made prior to the clarification could have
taken one of the other interpretations and would have to change
to be compliant with the clarified version.

So, I don't see how this definition is useful (unless it
is trying to say you can't have any useful clarifications 
in the errata but just updates to the non-nomative portions
of the spec -- which, in my opinion, would still be pretty
useless).
