Hi, I am writing doc for Image/Metadata. I created links to plug-in-metadata-editor and plug-in-metadata-viewer and got "Unknown ID" error message: *** Validating XML (en) ... -:53888: element link: validity error : IDREF attribute linkend references an unknown ID "plug-in-metadata-editor" -:53882: element xref: validity error : IDREF attribute linkend references an unknown ID "plug-in-metadata-viewer" Here are XML code samples: *** metadata.xml: <sect3> <title>The Metadata Submenu</title> <para> GIMP uses two plug-ins: <itemizedlist> <listitem> <para> <!--<xref linkend="plug-in-metadata-viewer"/>--> <link linkend="plug-in-metadata-viewer">Metadata Viewer</link>. </para> </listitem> <listitem> <para> <link linkend="plug-in-metadata-editor">Metadata Editor</link>. </para> </listitem> </itemizedlist> </para> </sect3> ----------------------------------------------------------- *** metadata-viewer.xml: <sect2 id="plug-in-metadata-viewer"> <title>Metadata Viewer</title> <!--<anchor id="plug-in-metadata-viewer"/>--> <indexterm> <primary>Metadata</primary> <secondary>Metadata Viewer</secondary> </indexterm> </sect2> ---------------------------------------------------------- *** metadata-editor.xml: <sect2 id="plug-in-metadata-editor"> <title>Metadata Viewer</title> <!--<anchor id="plug-in-metadata-editor"/>--> <indexterm> <primary>Metadata</primary> <secondary>Metadata Editor</secondary> </indexterm> </sect2> How to fix this error?
