+% Currently there is only a regionless style. \par
+% Actually, I think that it is not necessary to define variant styles (e.~g. "de-DE"\slash"de-DE-numeric" and "de-AT"\slash"de-AT-numeric") since there are --- as far as I know --- no differences in the \emph{format} of the date.
+% \par However, I'm only capable of standard German. If there \emph{are} differences in format and/or spelling, please create a feature request on GitHub or send me an e--mail. I would be very grateful, if some examples and/or a list of the weekdays' and months' spelling is/are also provided.
