In my previous post, I discussed what I believe is the outline data
structure in current use by outliners, and why they are inadequate for
my purposes. I discussed why transclusion doesn't work very well under
that model (an algorithm can sort of hack transclusion on top of the
tree, but it's not "real" enough), and the difficulties of replacing
some of the tree concepts when you have a full graph. Today's post
covers the "transclusion" issue.
