| 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>
|
|---|
| 54 |
|
|---|
| 55 | For example:
|
|---|
| 56 |
|
|---|
| 57 | <screen> <link rel="license" href="ln-id2524073.html" title="Legal Notice"></screen>
|

|
|---|
| 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>
