-<para>This parameter permits you
-to override the text to insert between
-the two numbers of a page range in an index.
-This parameter is only used by those XSL-FO processors
-that support an extension for generating such page ranges
-(such as XEP).</para>
-
-<para>Because this text may be locale dependent,
-this parameter's value is normally taken from a gentext
-template named 'range-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. So there are no page ranges
-and this parameter has no effect.
