+  ...
+  9. Return ! CreateArrayFromList( list ).
+
+  AvailableUnits ( )
+    The AvailableUnits abstract operation returns a List, ordered as if an Array
+    of the same values had been sorted using %Array.prototype.sort% using
+    undefined as comparefn, that contains the unique values of simple unit
+    identifiers listed in every row of Table 1, except the header row.
