(3) The units of a document form an ordered tree with the order

the first line of the unit. The root is an empty unit with
level zero which nominally appears at the beginning of the
document. A barrier between two units is a unit appearing
between those units which has level no greater than that of
the unit appearing first. One unit is a descendant of
another unit if it appears after the latter, has strictly
greater level, and is not separated from the latter by a
barrier.
I'm reluctant to make indentation matter, since that could interfere
with the rulekeepor's ability to make formatting changes. I'll give
this some thought, though.
