Using CSS, one can also give UL and OL a top margin that will draw it
closer to
the preceding paragraph. Neither this nor DIV really defines a
relationship in terms of meaning, just a physical grouping.

I can see it's a tree of elements. But excepting text-level elements,
not very treeish in terms of structuring content in terms of meaning.
You can't consider a heading a general idea and follow branches from
the general to the specifics. Most documents are one-parent families
with sterile children.
