But I am still not clever enough to grasp it. For
"<span><div></div><div></div></span>", what is pratically preventing
it from being a sane document tree, so that it has to be defined
invalid in HTML 4.01? The key word is "infeasible". So far, I can
only explain to myself that mixing the order of close-tag will make
DOM not a tree and therefore, wrong.
