-<para>This parameter permits you to override the text to insert between
-page references in a formatted index entry.  Typically 
-that would be a comma and a space.
-</para>
-
-<para>Because this text may be locale dependent,
-this parameter's value is normally taken from a gentext
-template named 'number-separator' in the
-context 'index' in the stylesheet
-locale file for the language
-of the current document.
-This parameter can be used to override the gentext string,
-and would typically be used on the command line.
-This parameter would apply to all languages.
-</para>
-
-<para>So this text string can be customized in two ways.
-You can reset the default gentext string using
-the <parameter>local.l10n.xml</parameter> parameter, or you can
-override the gentext with the content of this parameter.
-The content can be a simple string, or it can be
-something more complex such as a call-template.
-</para>
-
-<para>In HTML index output, section title references are used instead of
-page number references.  This punctuation appears between
-such section titles in an HTML index.
