Despite the long explanation, it is not 100% clear whether the 'ending version' is _inclusive_ or _exclusive_ — i.e., whether the associated element will _still exist_ in the 'ending version' or not.

This was taken over from original wording.  Given the new starting/ending version separation, common sense somewhat dictates that the 'ending version' is meant _exclusive_, but I think we can be more clear on that.

For example:
> The second version number, referred to as the 'ending version', denotes the version in which the associated element is scheduled for removal; i.e., _the associated element MAY no longer exist in the 'ending version', but MUST exist in all prior versions._

There's a separate paragraph about removal below, but it has a stronger focus on _"without further notice"_.
