<refsection><info><title>Description</title></info>

<para>The value of
<parameter>html.head.legalnotice.link.types</parameter> is a
space-separated list of link types, as described in <link xlink:href="http://www.w3.org/TR/html401/types.html#type-links">Section 6.12
of the HTML 4.01 specification</link>. If the value of the
<parameter>generate.legalnotice.link</parameter> parameter is
non-zero, then the stylesheet generates (in the
<literal>head</literal> section of the HTML source) either a single
HTML <literal>link</literal> element or, if the value of the
<parameter>html.head.legalnotice.link.multiple</parameter> is
non-zero, one <literal>link</literal> element for each link type
specified. Each <literal>link</literal> has the following attributes:

<itemizedlist>
  <listitem>
    <para>a <tag class="attribute">rel</tag> attribute whose
    value is derived from the value of
    <parameter>html.head.legalnotice.link.types</parameter></para>
  </listitem>
  <listitem>
    <para>an <tag class="attribute">href</tag> attribute whose
    value is set to the URL of the file containing the
    <tag>legalnotice</tag></para>
  </listitem>
  <listitem>
    <para>a <tag class="attribute">title</tag> attribute whose
    value is set to the title of the corresponding
    <tag>legalnotice</tag> (or a title programatically
    determined by the stylesheet)</para>
  </listitem>
</itemizedlist>

For example:

<screen>  &lt;link rel="license" href="ln-id2524073.html" title="Legal Notice"&gt;</screen>
</para>

<refsection><info><title>About the default value</title></info>
  
  <para>In an ideal world, the default value of
  <parameter>html.head.legalnotice.link.types</parameter> would
  probably be “<literal>license</literal>”, since the content of the
  DocBook <tag>legalnotice</tag> is typically license
  information, not copyright information. However, the default value
  is “<literal>copyright</literal>” for pragmatic reasons: because
  that’s among the set of “recognized link types” listed in <link xlink:href="http://www.w3.org/TR/html401/types.html#type-links">Section
  6.12 of the HTML 4.01 specification</link>, and because certain
  browsers and browser extensions are preconfigured to recognize that
  value.</para>
