+\section{Data transmission}
+En transmission består af en række deltransmissioner som afhænger af
+brugerens handling.
+\begin{itemize}
+\item Klienten beder om en XMLMakro by-name.
+\item Serveren genererer makroen og sender den til klienten i en XML
+      stream. Forbindelsen lukkes efter end overførsel.
+\item Brugeren udfylder input felterne og trykker på ``commit'' eller
+      ``abort'' knappen.
+\item Hvis der blev trykket ``abort'' lukkes vinduet.
+\item Hvis der blev trykket ``commit'' genereres et XML dokument på
+      klienten indeholdene alle input felternes navne og deres tilhørende
+      værdier.
+\item Dette XML dokument sendes til serveren via en nyoprettet forbindelse.
+\item Serveren producerer en plaintext klump som repræsenterer
+\item Teksten sendes til klienten som appender til den PC-Praxis
+      journalfilen.
+\item Klienten svarer til serveren at alt gik godt (eller det modsatte) og
+      makrovinduet lukkes.
+\item Serveren lagrer dataene i en database hvis det gik godt.
