25 <para>In DocBook documents that conform to a schema older than V4.3, this parame
ter allows | |
26 <tag class="attribute">role</tag> to serve the purpose of specifying the cross r
eference style.</para> | |

28 <para>If non-zero, the <tag class="attribute">role</tag> attribute on | |

for this purpose. | |
