Actually, it very easy to solve if you solve it in the right place. You
need to augment the input schema (DTD, XSchema, whatever) so that it can
guide the grouping of things.

<!ELEMENT DL (!DTITEM)>
<!GROUP DTITEM (DT, DD)>

Given this document:

<DL>
  <DT>...</DT><DD>..</DD>
  <DT>...</DT><DD>..</DD>
  <DT>...</DT><DD>..</DD>
  <DT>...</DT><DD>..</DD>
</DL>

You get this tree:

DL
   DLITEM
      DT
      DD
   DLITEM
      DT
      DD
   DLITEM
      DT
      DD
   DLITEM
      DT
      DD

David Peterson may have invented this idea in the SGML context, but in
retrospect it is a straightforward application of the computer science
concept of "non-terminal" in a context-free-grammar.
