The language of an olink is determined by its nearest ancestor element with a <code class="sgmltag-attribute">lang</code> attribute, otherwise the value of the <em class="parameter"><code>l10n.gentext.default.lang</code></em> parameter. </p> <p>An olink database can contain target data for the same document in multiple languages. Each set of data has the same value for the <code class="sgmltag-element">targetdoc</code> attribute in the <code class="sgmltag-element">document</code> element in the database, but with a different <code class="sgmltag-element">lang</code> attribute value. </p> <p>When an olink is being resolved, the target is first sought in the document with the same language as the olink. If no match is found there, then this parameter is consulted for additional languages to try.</p> <p>The <a href="../html/olink.lang.fallback.sequence.html"><em class="parameter"><code>olink.lang.fallback.sequence</code></em></a> must be a whitespace separated list of lang values to try. The first one with a match in the olink database is used. The default value is empty.</p> <p>For example, a document might be written in German and contain an olink with <code class="literal">targetdoc="adminguide"</code>. When the document is processed, the processor first looks for a target dataset in the olink database starting with:</p> <div class="literallayout"><p><code class="literal"><document targetdoc="adminguide" lang="de"></code>.<br> </p></div> <p>If there is no such element, then the <a href="../html/olink.lang.fallback.sequence.html"><em class="parameter"><code>olink.lang.fallback.sequence</code></em></a> parameter is consulted. If its value is, for example, <span class="quote">“<span class="quote">fr en</span>”</span>, then the processor next looks for <code class="literal">targetdoc="adminguide" lang="fr"</code>, and then for <code class="literal">targetdoc="adminguide" lang="en"</code>. If there is still no match, it looks for <code class="literal">targetdoc="adminguide"</code> with no lang attribute. </p> <p>This parameter is useful when a set of documents is only partially translated, or is in the process of being translated. If a target of an olink has not yet been translated, then this parameter permits the processor to look for the document in other languages. This assumes the reader would rather have a link to a document in a different language than to have a broken link. </p> </div> </div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="olink.doctitle.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="links.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="olink.properties.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">olink.doctitle </td><td width="20%" align="center"><a accesskey="h" href="../index.html">Home</a></td><td width="40%" align="right" valign="top"> olink.properties</td></tr></table></div></body></html>
