IIUC, those sections state that, when a list or a dictionary is empty, not only the field value but the entire field is omitted.

Section 4.1 explicitly says: If the structure is a Dictionary or List and its value is empty (i.e., it has no members), do not serialize the field at all (i.e., omit both the field-name and field-value).
