+% \section{Further customization of styles}
+% There are a number of settings provided that can be used in \verb|\DTMlangsetup| to modify the date-time style. These are:
+% \begin{description}
+%	\item["dowdaysep"]%
+%	The separator between the day of week name and the day of month number.
+%
+%	\item["daymonthsep"]%
+%	The separator between the day and the month name
+%
+%	\item["monthyearsep"]%
+%	The separator between the month name and year
+%
+%	\item["datesep"]%
+%	The separator between the date numbers in the "numeric style"s
+%
+%	\item["timesep"]%
+%	The separator between hours, minutes and seconds
+%
+%	\item["datetimesep"]%
+%	The separator between the date and time for the full date-time format
+%
+%	\item["timezonesep"]%
+%	The separator between the time and zone for the full date-time format
+%
+%	\item["abbr"]%
+%	This is a boolean key. If "true", the month (and weekday name, if shown) is abbreviated.
+%
+%	\item["mapzone"]%
+%	This is a boolean key. If "true", the time zone mappings are applied.
+%
+%	\item["showdayofmonth"]%
+%	A boolean key that determines whether or not to show the day of the month
+%
+%	\item["showyear"]%
+%	A boolean key that determines whether or not to show the year
+%\end{description}
+%
+%
+% Although the keys listed here are \textit{defined} for all variant styles, it depends on \sty{datetime2}'s setup and the requested styles whether they're \textit{used}. \\
+% For more information about the \verb|\DTMlangsetup| command see the documentation of the main \sty{datetime2} package.
