2.6.5 is an interesting paragraph to me. I'm not sure I understand the point to it.
It seems to me that all of it is simply a suggestion.
There seems nothing of a requirement in there.
In other words, you can if you want to, and if you do, you need not do it any more than this, and this is not grounds for rejection. to crudely sum it up.
I certainly would have liked to be in on the motiviation for this language.
