After some thinking I believe this is how we handle multiple outputs.

State that variables in functions being discrete-time is a bit more c…

Note that \lstinline!rem! and \lstinline!mod! generate events but are not discrete-time expressions.
In other words, relations inside \lstinline!noEvent!, such as \lstinline!noEvent(x>1)!, are not discrete-time expressions.
\end{nonnormative}
\item
Unless inside \lstinline!noEvent!: Function calls where the function has annotation \lstinline!GenerateEvents = true! (\Cref{modelica:GenerateEvents}) and the output does not contain a subtype of \lstinline!Real!.
For a function call returning multiple return values (see \cref{output-formal-parameters-of-functions}) the variability is decided separately for each output.
These calls will generate events, \Cref{modelica:GenerateEvents}.
\item
The functions \lstinline!pre!, \lstinline!edge!, and \lstinline!change! result in discrete-time expressions.
\item
Expressions in functions behave as though they were discrete-time expressions.
Expressions in functions not having annotation \lstinline!GenerateEvents = true! (\Cref{modelica:GenerateEvents}), behave as though they were discrete-time expressions.

\end{itemize}

Inside an \lstinline!if!-expression, \lstinline!if!-clause, \lstinline!while!-statement or \lstinline!for!-clause, that is controlled by a non-discrete-time (that is continuous-time, but not discrete-time) switching expression and not in the body of a \lstinline!when!-clause, it is not legal to have assignments to discrete-time variables, equations between discrete-time expressions, or real elementary relations/functions that should generate events.
