+11.3.  Examples
+
+   The following addresses
+
+             fe80::1234 (on the 1st link of the node)
+             ff02::5678 (on the 5th link of the node)
+             ff08::9abc (on the 10th organization of the node)
+
+   would be represented as follows:
+
+             fe80::1234%1
+             ff02::5678%5
+             ff08::9abc%10
+
+   (Here we assume a natural translation from a zone index to the
+   <zone_id> part, where the Nth zone of any scope is translated into
+   "N".)
+
+   If we use interface names as <zone_id>, those addresses could also be
+   represented as follows:
+
+            fe80::1234%ne0
+            ff02::5678%pvc1.3
+            ff08::9abc%interface10
+
+   where the interface "ne0" belongs to the 1st link, "pvc1.3" belongs
+   to the 5th link, and "interface10" belongs to the 10th organization.
