+     sufficient, the order of collation elements can be changed with tailoring

+     This small example creates a collation based on the root locale with a
+     tailoring rule:
+<programlisting>
+<![CDATA[CREATE COLLATION custom (provider = icu, locale = 'und', rules = '&V << w <<< W');]]>
+</programlisting>
+     With this rule, the letter <quote>W</quote> is sorted after
+     <quote>V</quote>, but is treated as a secondary difference similar to an
+     accent.  Rules like this are contained in the locale definitions of some
+     languages.  (Of course, if a locale definition already contains the
+     desired rules, then they don't need to be specified again explicitly.)

+     characters in the order of the EBCDIC encoding.
