The software cares because X[HT]ML documents are hierarchical; every
element is contained within another element. In <b><i>..></i></b>,
the <i> element is contained within the <b> element; in
<i><b>...</b></i>, the reverse is true. In <b><i>...</b></i>, neither
element is contained within the other; they overlap. That's not
allowed becuase the model of the document built to enable processing of
it has no way to represent it. Which element is which's parent?
