+  Note that since the locale hierarchy reflects that total orders are
+  distributive lattices, an explicit interpretation of distributive
+  lattices for the order relation on natural numbers is not neccessary.
+
+  Why not push this idea further and just give the last interpretation
+  as a single interpretation instead of the sequence of three?  The
+  reasons for this are twofold:
+\begin{itemize}
+\item
+  Often it is easier to work in an incremental fashion, because later
+  interpretations require theorems provided by earlier
+  interpretations.
+\item
+  Assume that a definition is made in some locale $l_1$, and that $l_2$
+  imports $l_1$.  Let an equation for the definition be
+  proved in an interpretation of $l_2$.  The equation will be unfolded
+  in interpretations of theorems added to $l_2$ or below in the import
+  hierarchy, but not for theorems added above $l_2$.
+  Hence, an equation interpreting a definition should always be given in
+  an interpretation of the locale where the definition is made, not in
+  an interpretation of a locale further down the hierarchy.
