<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>
