<doc:template match="t:titlepage-content" id="titlepage-content">
<refpurpose>Create templates for the content of one side of a title page</refpurpose>

<refdescription>
<para>The title page content, that is, the elements from the source
document that are rendered on the title page, can be controlled independently
for the recto and verso sides of the title page.</para>

<para>The <literal>t:titlepage-content</literal> element has two attributes:

<variablelist>
<varlistentry><term>side</term>
<listitem><para>Identifies the side of the page to which this title
page content applies. The
<tag class="attribute">side</tag> attribute is required and
must be set to either 
<quote><literal>recto</literal></quote> or
<quote><literal>verso</literal></quote>. In addition, you must specify
exactly one <literal>t:titlepage-content</literal> for each side
within each <literal>t:titlepage</literal>.</para>
</listitem>
</varlistentry>
<varlistentry><term>order</term>
<listitem><para>Indicates how the order of the elements presented on
the title page is determined. If the
<tag class="attribute">order</tag> is
<quote><literal>document</literal></quote>, the elements are presented
in document order. Otherwise (if the
<tag class="attribute">order</tag> is
<quote><literal>stylesheet</literal></quote>), the elements are presented
in the order that they appear in the template (and consequently in
the stylesheet).</para>
</listitem>
</varlistentry>
</variablelist>
</para>

<para>The content of a <literal>t:titlepage-content</literal> element is
a list of element names. These names should be unqualified.  They identify
the elements in the source document that should appear on the title page.
</para>

<para>Each element may have a single attribute:
<tag class="attribute">predicate</tag>. The value of this
attribute is used as a predicate for the expression that matches
the element on which it occurs.</para>

<para>In other words, to put only the first three authors on the
recto-side of a title
page, you could specify:

<screen><![CDATA[
  <t:titlepage-contents side="recto">
    <!-- other titlepage elements -->
    <author predicate="[count(previous-sibling::author)<2]"/>
    <!-- other titlepage elements -->
  </t:titlepage-contents>
]]></screen>
</para>

<para>Usually, the elements so named are empty. But it is possible to
make one level of selection within them. Suppose that you want to
process <literal>authorgroup</literal> elements on the title page, but
you want to select only proper authors, editors, or corporate authors,
not collaborators or other credited authors.</para>

<para>In that case, you can put a <literal>t:or</literal> group inside
the <literal>authorgroup</literal> element:

<screen><![CDATA[
  <t:titlepage-contents side="recto">
    <!-- other titlepage elements -->
    <authorgroup>
      <t:or>
        <author/>
        <editor/>
        <corpauthor/>
      </t:or>
    </authorgroup>
    <!-- other titlepage elements -->
  </t:titlepage-contents>
]]></screen>
</para>

<para>This will have the effect of automatically generating a template
for processing <literal>authorgroup</literal>s in the title page mode,
selecting only the specified children. If you need more complex processing,
you'll have to construct the templates by hand.</para>
