I don't think that any specification will stop people who wish to behave 
egregiously from doing so. I think part of the document's purpose is to 
define more clearly what the consensus view is on what constitutes 
egregious behaviour.

Hmmm, yes we spend a lot of energy on wording - not wasted in my view. I 
also think that we removed details of white lists not because we 
couldn't get consensus otherwise (after all, if people feel that white 
lists should be mentioned then leaving them out would not constitute 
consensus). The reason for removing reference to white lists is because 
we can discuss the effects of white lists without making specific 
reference to them. It's desirable in my view to avoid reference to the 
assumed internal operation of systems, and instead to refer to their 
observable behaviour.

Well, that one is certainly up for grabs, I think, because of the point 
about wanting to define observable behaviour rather than internal 
operation. I don't have a particular problem with including further 
heuristics but equally think that those included at present were chosen 
for good reason. Certainly one to revisit though.

We made a good start on this in the Appendices. More can undoubtedly be 
done.
