+  <section title="State Operations">
+    For operations that involve taking values of all states where order
+      matters (e.g. for index alignment),
+        querying the symbol table isn't appropriate,
+          as it does not guarantee order.
+    \ref{_for-each-state_} can be used for that purpose;
+      it exposes the following template values to its body:
+
+    \begin{enumerate}
+      \item \tt{@state_const@} contains the State constant;
+      \item \tt{@state_upper@} contains the uppercase two-letter State
+              abbreviation;
+      \item \tt{@state_lower@} contains the lowercase two-letter State
+              abbreviation; and
+      \item \tt{@state_name@} contains the full state name.
+    \end{enumerate}
+
+    This can be used to generate a ^[State vector] by mapping an iteration
+      index to the State constant~\tt{@state_const@}.
+    Note that \ref{STATE_NONE} is not in the list.
