I'm not sure that I see the problem. The clause is definitional, not procedural. Would it help if "considered" were replaced with "conceptually organized"?
It would help eliminate some ambiguity. I suggest something like the following. (3) The units of a document form an ordered tree with the order determined as follows. Each unit has a level, which is the number of spaces preceding the first non-space character on 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. This expresses the fact that given a total order O and a function r of O into the natural numbers, there is a natural way to partially order the elements of O as a tree whose (gappy) grading is given by r, which seems to be what the various versions of (d) (3) are trying to say. I know that what I wrote is wordier than previous versions. I think it is somewhat clearer. I'm not certain that I've captured the exact definition intended, since I'm not used to a ``section'' being part of a ``paragraph''. -- C. Maud Image (Michael Slone) I'm on vacation.
