Dear Martin, Thank you for this extension of the scope notes. I think it makes a lot of sense but I have similar comments as to E4.
If the SIG thinks my suggestions for the changes to your proposal for E4 is useful I will be happy to make similar changes to the fourth paragraph (“Even though the substance of an instance...”) here in E18.
