<para>In DocBook documents that conform to a schema older than V4.3, this parameter allows 
<tag class="attribute">role</tag> to serve the purpose of specifying the cross reference style.</para>

<para>If non-zero, the <tag class="attribute">role</tag> attribute on
<tag>xref</tag> will be used to select the cross reference style.
In DocBook V4.3, the <tag class="attribute">xrefstyle</tag> attribute was added for this purpose.
If the <tag class="attribute">xrefstyle</tag> attribute is present, 
<tag class="attribute">role</tag> will be ignored, regardless of the setting
of this parameter.</para>

<para>The following small stylesheet shows how to configure the
stylesheets to make use of the cross reference style:</para>

<programlisting>&lt;?xml version="1.0"?&gt;
&lt;xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                version="1.0"&gt;

&lt;xsl:import href="../xsl/html/docbook.xsl"/&gt;

&lt;xsl:output method="html"/&gt;

&lt;xsl:param name="local.l10n.xml" select="document('')"/&gt;
&lt;l:i18n xmlns:l="http://docbook.sourceforge.net/xmlns/l10n/1.0"&gt;
  &lt;l:l10n xmlns:l="http://docbook.sourceforge.net/xmlns/l10n/1.0" language="en"&gt;
   &lt;l:context name="xref"&gt;
      &lt;l:template name="chapter" style="title" text="Chapter %n, %t"/&gt;
      &lt;l:template name="chapter" text="Chapter %n"/&gt;
    &lt;/l:context&gt;
  &lt;/l:l10n&gt;
&lt;/l:i18n&gt;

&lt;/xsl:stylesheet&gt;</programlisting>

<para>With this stylesheet, the cross references in the following document:</para>

<programlisting>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.2//EN"
                  "http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd"&gt;
&lt;book id="book"&gt;&lt;title&gt;Book&lt;/title&gt;

&lt;preface&gt;
&lt;title&gt;Preface&lt;/title&gt;

&lt;para&gt;Normal: &lt;xref linkend="ch1"/&gt;.&lt;/para&gt;
&lt;para&gt;Title: &lt;xref xrefstyle="title" linkend="ch1"/&gt;.&lt;/para&gt;

&lt;/preface&gt;

&lt;chapter id="ch1"&gt;
&lt;title&gt;First Chapter&lt;/title&gt;

&lt;para&gt;Irrelevant.&lt;/para&gt;

&lt;/chapter&gt;
&lt;/book&gt;</programlisting>

<para>will appear as:</para>

<informalexample>
<para>Normal: Chapter 1.</para>
<para>Title: Chapter 1, <emphasis>First Chapter</emphasis>.</para>
