This is not just an issue for errata management.  The difference between 
and editorial and substantive changes also determines whether a 
Candidate REC is published as a Revised Candidate Recommendation and 
goes through another exclusion period or not (Process section 7.4.1).  
We seem to think we can tell the difference when a spec is being 
developed and goes to CR and needs to change again.  We should clarify 
the definition of Editorial Changes (I propose a definition below).

I think the 2 separate classes that make up editorial changes used to be 
treated differently, but not anymore so those separate classes aren't 
needed. Coalescing them makes 3 classes that are treated differently (1. 
editorial changes -> ?; 2. substantive changes that don't add features 
-> CR; 3. substantive changes that do add new features -> FPWD)

Suggestion for Definition of Editorial Changes:
Editorial Changes are modifications that do not affect conformance.  
Reasonable implementers would not interpret these modifications as 
changing architectural or interoperability requirements. If 
implementation requirements were ambiguous and were made clear by a 
modification, then that modification is not considered an Editorial 
Change because it may be viewed as changing requirements. If there is 
any doubt as to whether a modification is an Editorial Change, it should 
not be considered an Editorial Change. Examples of Editorial Changes are 
fixing links, typos or grammatical errors where the change does not 
change implementation requirements.  Other examples include correcting 
non-normative code examples where the code clearly conflicts with 
normative requirements, or clarifying informative use cases or other 
non-normative text that does not define implementation requirements.   
As a rule of thumb, Editorial Changes do not require any code changes in 
reasonably competent implementations.

With a good definition for what the classification is, we could then 
decide who decides on which class modifications to a spec fall into 
(either a CR that changes on the way to REC or a revised REC later).

An AC rep of a member with a significant IP portfolio has to do a lot of due diligence for the process to be effective, and the actual work has to be done by people who understand patent law and the member's portfolio.  That's expensive, but has to be weighed against the expected cost/benefits of the portfolio.

I have worked for companies that active discourage knowledge of patents by their employees. That would mean that an AC rep for such a company would not have the knowledge to trigger an exclusion period. It seems safer to just have the exclusion period which would provide greater patent protection because expiration of the exclusion period would require any patent owned by a group Member to have a royalty free license in the future. That is why I think the issue reduces down to (a) require exclusion period or (b) do not require exclusion period.
