Note
For this element, the global n attribute indicates the new number or other value for the unit which changes at this milestone. The special value unnumbered should be used in passages which fall outside the normal numbering scheme, such as chapter or other headings, poem numbers or titles, etc.
The order in which milestone elements are given at a given point is not normally significant.
