Chunks are noun or prepositional phrases, spanning terms.\\

The \texttt{<chunk>} element has the following attributes:
\begin{itemize}
\item \texttt{id} (\textbf{required}): unique identifier, starting with the prefix ``c''.
\item \texttt{head} (\textbf{required)}: the id of the chunk's head.
\item \texttt{phrase} (optional): type of the phrase.
\item \texttt{case} (optional): declension case.
\end{itemize}
