refentry.date.profile — Specifies profile for refentry "date" data
<xsl:param name="refentry.date.profile"> ($info/date |$info/pubdate |$parentinfo/date |$parentinfo/pubdate)[1]/node() </xsl:param>
The value of refentry.date.profile is a
string representing an XPath expression. It is evaluated at run-time
and used only if refentry.date.profile.enabled
is non-zero. Otherwise, the refentry metadata-gathering
logic "hard coded" into the stylesheets is used.
The man(7) 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.
