          If set to <literal>true</literal>, numbers within a string are
          treated as a single numeric value rather than a sequence of
          digits. For example, <literal>'id-45'</literal> sorts before
          <literal>'id-123'</literal>.

           Enable full normalization; may affect performance. Basic
           normalization is performed even when set to
           <literal>false</literal>. Locales for languages that require full
           normalization typically enable it by default.
          </para>
          <para>
           Full normalization is important in some cases, such as when
           multiple accents are applied to a single character. For example,
           the code point sequences <literal>U&amp;'\0065\0323\0302'</literal>
           and <literal>U&amp;'\0065\0302\0323'</literal> represent
           an <literal>e</literal> with circumflex and dot-below accents
           applied in different orders. With full normalization
           on, these code point sequences are treated as equal; otherwise they
           are unequal.

           Redefines the ordering of classes of characters; those characters
           belonging to a class earlier in the list sort before characters
           belonging to a class later in the list. For instance, the value
           <literal>digit-currency-space</literal> (as part of a language tag
           like <literal>und-u-kr-digit-currency-space</literal>) sorts
           punctuation before digits and spaces.

          Classes of characters ignored during comparison at level 3. Setting
          to a later value includes earlier values;
          e.g. <literal>symbol</literal> also includes
          <literal>punct</literal> and <literal>space</literal> in the
          characters to be ignored. Key <literal>ka</literal> must be set to
          <literal>shifted</literal>
