-Areas that correspond to parts of @dfn{subtables}, whose contents are
-the cells that pair an innermost row variable and an innermost column
-variable within a single layer. A section can contain multiple
-subtables and a subtable is always within a single section:
+The following shows how the output for the table expression @code{qn61
+> qn57 BY qnd7a > qn86 + qn64b BY qns3a}@footnote{This is not
+necessarily a meaningful table, so for clarity variable labels are
+omitted.} is divided up into @code{TABLE}, @code{LAYER}, and
+@code{SUBTABLE} areas. Each unique value for Table ID is one section,
+and similarly for Layer ID and Subtable ID. Thus, this output has two
+@code{TABLE} areas (one for @code{qnd7a} and one for @code{qn64b}),
+four @code{LAYER} areas (for those two variables, per layer), and 12
+@code{SUBTABLE} areas.
