I agree that the prototype is not correct in this respect.  I
originally planned to separate orgmode elements into two types:
ordered and unordered.  Unordered elements would be things like
plain lists and headings.  Ordered entities would be things like
numbered plain lists.

This decision led to the prototype not tracking the order which
headings appear.  Only hierachical position was tracked and used
in the prototype.  As a result, new headings are always shown at
the start of a level, and reordered headings may or may show up
in the new order.  I have since changed my mind about how to
handle this situation.

The new strategy is to track the same positional data for both
ordered and unordered elements.  The difference between the
element types will be in how reorders from both files will be
merged together.

I can modify the prototype to print headings in the correct
order, but I'm mostly just interested in moving on.

Sincerely,
Andrew
