The description refers to controlled zones in context-sensitive contexts. The description ends with parentheses in a context with [box] and temporal markers, indicating the context is controlled by [s], [z], [p], and the details contain [e], [r], etc., indicating it is a controlled zone.
The description could refer to controlled zones in controlled contexts but appears in a controlled zone at the end with square brackets, indicating it is a controlled zone in a controlled zone.
But in the initial part, in the negative zone (formula) before the box-ins, meaning it’s at the start (s before 0) of the formula, outside parentheses, but in the controlled zone, perhaps it is discussed using wrap.
Overall, honestly, the description is in a context that is a controlled zone in an controlled zone.
Answer: Controlled zones.
