  \item [The Title] The rest of the text.  This is a rather uninteresting
        sentence, but it servers to go on long enough to wrap around and
        that was the purpose.
    \begin{enumerate}
      \item Number One
        \begin{itemize}
          \item A bullet point.
          \item Another bullet point.
          \item Number One
        \end{itemize}
      \item Number Two
    \end{enumerate}
  \item [The Title] The beginning of a second bit.
