<h2>lenient-xpath</h2>

<p>By default XPath evaluation throws an exception if the supplied XPath does
not map to an existing property. This constraint can be relaxed by setting the
parameter <tt>lenient-xpath</tt> to <tt>true</tt>. In the lenient mode
evaluation simply returns null if the path maps to nothing.</p>

<p>Example:</p>

<pre>    &lt;map:match pattern="*.jx"&gt;
      &lt;map:generate type="jx" src="documents/{1}.jx"&gt;
           &lt;map:parameter name="lenient-xpath" value="true"/&gt;
      &lt;/map:generate&gt;
      &lt;map:serialize type="xhtml"/&gt;
    &lt;/map:match&gt;
</pre>
