DITA OT PDF插件通知格式定制：legal属性主题前置打印

我是DITA OT新手，正在开发自定义PDF插件。我的ditamap中有设置otherprops='legal'的topicrefs关联主题，希望将这些主题在目录（TOC）前用不同的母版页打印。我认为这正是notices主题类型的用途，若有误请指正！

我尝试过以下操作，但没有可见效果：

• 修改commons.xsl中的determineTopicType模板，添加或条件以捕获map中含otherprops='legal'的topicrefs
• 修改processTopicNotices模板使用新属性集
• 在commons-attr.xsl和topic-attr.xsl中定义这些属性集

我也曾尝试创建新母版页和页面序列并在主题处理时应用，但觉得topic notices功能正是为此场景设计，遂放弃避免重复造轮子。目前我正尝试利用notices功能让这些topicrefs在通知页面和页面序列中打印。以下是更新后的代码：

<xsl:template match="*[contains(@class, ' bookmap/notices ') or @otherprops='legal']" mode="determineTopicType">
    <xsl:text>topicNotices</xsl:text>
</xsl:template>

<xsl:template name="processTopicNotices">
    <xsl:variable name="atts" as="element()">
        <xsl:choose>
            <xsl:when test="key('map-id', ancestor-or-self::*[contains(@class, ' topic/topic ')][1]/@id)/ancestor::*[contains(@class,' bookmap/backmatter ')]">
                <dummy xsl:use-attribute-sets="page-sequence.backmatter.notice"/> 
            </xsl:when>
            <xsl:otherwise>
                <dummy xsl:use-attribute-sets="page-sequence.notice"/> 
            </xsl:otherwise>
        </xsl:choose>
    </xsl:variable>
    <fo:page-sequence master-reference="body-sequence">
