Not quite, unless there's a typo in the standard:

  (element-number snl)

  Returns the number of elements before or equal to snl with the same gi
  as snl.

This is great for numbering, say, chapters within a part:

  Part I
    Chapter 1
    Chapter 2
    Chapter 3
  Part II
    Chapter 4
    Chapter 5
    Chapter 6

Where (child-number snl) would give you

  Part I
    Chapter 1
    Chapter 2
    Chapter 3
  Part II
    Chapter 1
    Chapter 2
    Chapter 3

However, it does nothing for Eliot's problem.


All the best,


David
