For example, the markup:</para> <screen><section id="foo"><title>Some Title</title> <para>Some para.</para> </section></screen> <para>might produce:</para> <screen><div class="section" id="foo"> <h2>Some Title</h2> <p>Some para.</p> </div></screen> <para>The alternative is to generate anchors:</para> <screen><div class="section"> <h2><a name="foo"></a>Some Title</h2> <p>Some para.</p> </div></screen> <para>Because the <tag class="attribute">name</tag> attribute of the <tag>a</tag> element and the <tag class="attribute">id</tag> attribute of other tags are both of type <quote>ID</quote>, producing both generates invalid documents.</para> <para>As of version 1.50, you can use this switch to control which type of identifier is generated. For backwards-compatibility, generating <tag>a</tag> anchors is preferred.</para> <para>Note: at present, this switch is incompletely implemented. Disabling ID attributes will suppress them, but enabling ID attributes will not suppress the anchors.</para> </refsection> </refentry>
