24 <para>The value of
25 <parameter>html.head.legalnotice.link.types</parameter> is a
26 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
27 of the HTML 4.01 specification</link>. If the value of the
28 <parameter>generate.legalnotice.link</parameter> parameter is
29 non-zero, then the stylesheet generates (in the
30 <literal>head</literal> section of the HTML source) either a single
31 HTML <literal>link</literal> element or, if the value of the
32 <parameter>html.head.legalnotice.link.multiple</parameter> is
33 non-zero, one <literal>link</literal> element for each link type
34 specified. Each <literal>link</literal> has the following attributes:
35
36 <itemizedlist>
37   <listitem>
38     <para>a <tag class="attribute">rel</tag> attribute whose
39     value is derived from the value of
40     <parameter>html.head.legalnotice.link.types</parameter></para>
41   </listitem>
42   <listitem>
43     <para>an <tag class="attribute">href</tag> attribute whose
44     value is set to the URL of the file containing the
45     <tag>legalnotice</tag></para>
46   </listitem>
47   <listitem>
48     <para>a <tag class="attribute">title</tag> attribute whose
49     value is set to the title of the corresponding
50     <tag>legalnotice</tag> (or a title programatically
51     determined by the stylesheet)</para>
52   </listitem>
53 </itemizedlist>

55 For example:
56
57 <screen>  &lt;link rel="license" href="ln-id2524073.html" title="Legal Notice"&gt;</screen>
58 </para>
59
60 <refsection><info><title>About the default value</title></info>
61   
62   <para>In an ideal world, the default value of
63   <parameter>html.head.legalnotice.link.types</parameter> would
64   probably be “<literal>license</literal>”, since the content of the
65   DocBook <tag>legalnotice</tag> is typically license
66   information, not copyright information. However, the default value
67   is “<literal>copyright</literal>” for pragmatic reasons: because
68   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
69   6.12 of the HTML 4.01 specification</link>, and because certain
70   browsers and browser extensions are preconfigured to recognize that
71   value.</para>
