<p>The value of
<a href="../manpages/refentry.source.fallback.profile.html"><em class="parameter"><code>refentry.source.fallback.profile</code></em></a> is a string
representing an XPath expression. It is evaluated at run-time and used
only if no "source" data can be found by other means (that is, either
using the <a href="http://docbook.org/tdg5/en/html/refentry.html"><code class="sgmltag-element">refentry</code></a> metadata-gathering logic "hard coded" in
the stylesheets, or the value of the
<a href="../manpages/refentry.source.name.profile.html"><em class="parameter"><code>refentry.source.name.profile</code></em></a> and
<a href="../manpages/refentry.version.profile.html"><em class="parameter"><code>refentry.version.profile</code></em></a> parameters, if those
are enabled).</p>
<div class="important" title="Important" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Important</h3>
<p>Depending on which XSLT engine you run, either the EXSLT
<code class="function">dyn:evaluate</code> extension function (for xsltproc or
Xalan) or <code class="function">saxon:evaluate</code> extension function (for
Saxon) are used to dynamically evaluate the value of
<a href="../manpages/refentry.source.fallback.profile.html"><em class="parameter"><code>refentry.source.fallback.profile</code></em></a> at
run-time. If you don't use xsltproc, Saxon, Xalan -- or some other
XSLT engine that supports <code class="function">dyn:evaluate</code> -- you
must manually disable fallback processing by setting an empty value
for the <a href="../manpages/refentry.source.fallback.profile.html"><em class="parameter"><code>refentry.source.fallback.profile</code></em></a>
parameter.</p>
