+\chapter{Creating Specifications with \LaTeX}
+This chapter is an example of an implementation of the specifications and is
+useful as an API reference, but \shallnot be used in place of formal
+specifications with regards to implementation.
+
+Using the {\tt dwspec} document class with enable paragraph numbering; {\tt
+draft} mode will enable signature lines, as shown to the right.
+
+\begin{ex}
+  \begin{verbatim}
+% omit "[draft]" to disable unapproved signature lines
+\documentclass[draft]{lvspec}
+
+% as is the case with all LaTeX documents, begin and end with document
+% environment
+\begin{document}
+  % ...content here...
+\end{document}
+  \end{verbatim}
+\end{ex}
+
+Example environments, as shown above, can be created with the {\tt ex}
+environment. All examples end with `$\square$'.
+
+\begin{ex}
+  \begin{verbatim}
+\begin{ex}
+  % ...example here...
+\end{ex}
+  \end{verbatim}
+\end{ex}
+
+
+\section{Paragraph Numbering}
+Paragraph numbering can be temporarily disabled using \verb|\pnumoff| and
+re-enabled using \verb|pnumon|\ldots
+
+\pnumoff
+\ldots as shown here.
+
+\pnumon
+Numbers will continue where they previously left off before being suppressed.
+
+Disabling paragraph numbering also disables the signature line
+
+\begin{ex}
+  \begin{verbatim}
+Paragraph numbering can be temporarily disabled using \verb|\pnumoff| and
+re-enabled using \verb|pnumon|\ldots
+
+\pnumoff
+\ldots as shown here.
+
+\pnumon
+Numbers will continue where they previously left off before being suppressed.
+  \end{verbatim}
+\end{ex}
+
+
+\section{Signature Lines}
+The department for the entire section can be set using the
+\verb|\sectiondept| command; the command takes effect until the next section
+or chapter.
+
+\begin{ex}
+  \begin{verbatim}
+\section{Signature Lines}
+\sectiondept{it}
+The department for the entire section can be set using the
+\verb|\sectiondept| command; the command takes effect until the next section
+or chapter.
+  \end{verbatim}
+\end{ex}
+
+\dept{pm}
+The department can be set per-paragraph using the \verb|\dept| command, as
+demonstrated in this paragraph; the command will override any
+\verb|\sectiondept| command temporarily and will undo itself after the paragraph
+ends.
+
+\begin{ex}
+  \begin{verbatim}
+\dept{pm}
+The department can be set per-paragraph using the \verb|\dept| command, as
+demonstrated in this paragraph; the command will override any
+\verb|\sectiondept| command temporarily and will undo itself after the paragraph
+ends.
+  \end{verbatim}
+\end{ex}
+
+\dept{it}
+An arbitrary group of paragraphs may have their section set using
+\verb|\begindeptgroup| and \verb|\enddeptgroup|; they are \emph{not} reset by
+sections. They may be nested.
+
+\begin{ex}
+  \begin{verbatim}
+\begindeptgroup{it}
+  % group: it
+  \begindeptgroup{pm}
+    % group: pm
+  \enddeptgroup
+  % group: it
+\enddeptgroup
+  \end{verbatim}
+\end{ex}
+
+Clicking on the department in the signature line will take you to the
+^[authorization parties] section of the definitions (in this document,
+\sref{authorize}).
+
+\subsection{Incomplete}
+\incomplete
+If a paragraph is incomplete and not yet ready for authorization, use
+\verb|\incomplete|.
+
+\begin{ex}
+  \begin{verbatim}
+\incomplete
+If a paragraph is incomplete and not yet ready for authorization, use
+\verb|\incomplete|.
+  \end{verbatim}

+command \verb|\incompletei|, which also includes the name of the department.
