The valid distinction seems to be that DocBook gives a tree structure to the mark-up which troff does not. A tree structure could be inferred from knowledge of the macros meaning for a particular macro set but the mark-up itself doesn't create one. (See vi's `:set paragraphs?'.) Having a tree structure allows one to do wholesale modifications, e.g. move a branch AKA paragraph. That said, I much prefer troff's quiet mark-up than the unworkable noise of DocBook. Cheers, Ralph.
