 If \lstinline!connectorSizing = true!, a tool may set the variable value in a modifier automatically, if used as dimension size of a vector of connectors.
 In that case the value modifier should not be edited directly by the user, and a tool may choose to not display that variable in the dialog or display it with disabled input field.
+There shall be exactly one vector of connectors using the dimension size \lstinline!n! for each variable \lstinline!n! with \lstinline!connectorSizing = true!.
+Other vectors of connectors that need to have the same size may use a different expression with the same value, such as \lstinline!n + 0!, to avoid that multiple vectors become associated with the \lstinline!connectorSizing! automatic updating of \lstinline!n!.
+(Note that non-connector vectors may have size \lstinline!n! without becoming associated.)
 
 \begin{nonnormative}
 The \lstinline!connectorSizing! annotation is used in cases where connections to a vector of connectors shall be made and a new connection requires to resize the vector and to connect to the new index (unary connections).
 The annotation allows a tool to perform these two actions in many cases automatically.
 This is, e.g., very useful for state machines and for certain components of fluid libraries.
+
+If a variable \lstinline!n! with \lstinline!connectorSizing = true! does not have exactly one associated vector of connectors, a diagnostic is recommended.
+If there are no vector of connectors for such a variable it should be removed.
+Having multiple vector of connectors for such a variable will not work reliably for all graphical operations described below.
