      Bug#37129 LDML lacks <i> rule
      Problem: LDML didn't understand '<i>' tag in
      character set definition file Index.xml.
      Manual incorrectly used '<s>' instead of '<i>' in:
      http://dev.mysql.com/doc/refman/5.1/en/adding-collation-unicode-uca.html
      Fix: Adding support for '<i>' tag.
      Manual should be changed accordingly.
