Acceptance of the Resolution for 19840 under Ballot 4 in the second half of 2016 resulted in the following text being substituted for a Note in the entry for Advice of Possibility.
Note: Every definitional rule implies an advice of possibility. Consider the definitional rule expressed as:
It is necessary that each rental has exactly one car group.
Each rental always has exactly one car group.
This definitional rule implies an advice of possibility that can be expressed as:
It is possible that a rental has exactly one car group.
A rental can have exactly one car group.
There is no practical reason, however, to express the advice of possibility implied by a definitional rule explicitly. In such cases, best practice generally favors keeping the number of elements of guidance to be managed to a minimum.
The equivalent substitution needs to be done for Advice of Permission. It’s just a clarification of the Note, which is otherwise somewhat hard to decipher
