+      The URL attribute holds the URL that points from the index entry
+      back to the appropriate place in the output produced by the HTML
+      stylesheet. (It's much easier to calculate this URL in the first
+      pass.)
+
+      The Role attribute holds the ID (either real or manufactured) of
+      the corresponding INDEXTERM.  This is used by the print backends
+      to produce page numbers.
+
+      The entries below are sorted and collated into the correct order.
+      Duplicates may be removed in the HTML backend, but in the print
+      backends, it is impossible to suppress duplicate pages or coalesce
+      sequences of pages into a range.
