<refsect1><title>Description</title>

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

<para>A "source name" is one part of a (potentially) two-part
<replaceable>Name</replaceable>&#160;<replaceable>Version</replaceable>
"source" field. In man pages, it is usually displayed in the left
footer of the page. The <literal>man(7)</literal> man page describes
this as "the source of the command", and provides the following
examples:
<itemizedlist>
  <listitem>
    <para>For binaries, use something like: GNU, NET-2, SLS
    Distribution, MCC Distribution.</para>
  </listitem>
  <listitem>
    <para>For system calls, use the version of the kernel that you
    are currently looking at: Linux 0.99.11.</para>
  </listitem>
  <listitem>
    <para>For library calls, use the source of the function: GNU, BSD
    4.3, Linux DLL 4.4.1.</para>
  </listitem>
</itemizedlist>
</para>

<para>In practice, there are many pages that simply have a Version
number in the "source" field. So, it looks like what we have is a
two-part field,
<replaceable>Name</replaceable>&#160;<replaceable>Version</replaceable>,
where:
<variablelist>
  <varlistentry>
    <term>Name</term>
    <listitem>
      <para>product name (e.g., BSD) or org. name (e.g., GNU)</para>
    </listitem>
  </varlistentry>
  <varlistentry>
    <term>Version</term>
    <listitem>
      <para>version number</para>
    </listitem>
  </varlistentry>
</variablelist>
Each part is optional. If the <replaceable>Name</replaceable> is a
product name, then the <replaceable>Version</replaceable> is probably
the version of the product. Or there may be no
<replaceable>Name</replaceable>, in which case, if there is a
<replaceable>Version</replaceable>, it is probably the version
of the item itself, not the product it is part of. Or, if the
<replaceable>Name</replaceable> is an organization name, then there
probably will be no <replaceable>Version</replaceable>.</para>
