<para>The value of <parameter>refentry.date.profile</parameter> is a
string representing an XPath expression. It is evaluated at run-time
and used only if <parameter>refentry.date.profile.enabled</parameter>
is non-zero. Otherwise, the <tag>refentry</tag> metadata-gathering
logic "hard coded" into the stylesheets is used.</para>

<para> The <literal>man(7)</literal> man page describes this content
as "the date of the last revision". In man pages, it is the content
that is usually displayed in the center footer.</para>
