我正在使用XSLT和XSL-FO来创建文档。并且要求是：在文档中，页码应该从第2页开始（第2页上的数字应该是1）。
在layout-master-set中我创建了2个simple-page-master并尝试以下方式：
<fo:layout-master-set>
<fo:simple-page-master master-name="cover" page-height="11in" page-width="8.5in">
<fo:region-body margin="0.1in 1.0in 0.45in 1.0in"/>
</fo:simple-page-master>
<fo:simple-page-master master-name="master" page-height="11in" page-width="8.5in">
<fo:region-body margin="0.1in 1.0in 0.45in 1.0in"/>
<fo:region-after region-name="footer-first1" extent="1.2in"/>
</fo:simple-page-master>
<fo:page-sequence-master master-name="CoverPage1">
<fo:repeatable-page-master-alternatives>
<fo:conditional-page-master-reference master-reference="cover" page-position="first" />
</fo:repeatable-page-master-alternatives>
</fo:page-sequence-master>
<fo:page-sequence-master master-name="CoverPage">
<fo:repeatable-page-master-alternatives>
<fo:conditional-page-master-reference master-reference="cover" page-position="first" />
<fo:conditional-page-master-reference master-reference="master" page-position="rest"/>
</fo:repeatable-page-master-alternatives>
</fo:page-sequence-master>
</fo:layout-master-set>
<fo:page-sequence master-reference="CoverPage1">
<fo:flow flow-name="xsl-region-body">
<xsl:apply-templates/>
</fo:flow>
</fo:page-sequence>
<fo:page-sequence initial-page-number="1" master-reference="CoverPage">
<fo:static-content flow-name="footer-first1">
<xsl:call-template name="footer1"/>
</fo:static-content>
<fo:flow flow-name="xsl-region-body">
<xsl:apply-templates/>
</fo:flow>
</fo:page-sequence>
</fo:root>
</xsl:template>
和页脚：
<xsl:template name="footer1">
<fo:block font-family="Times" text-align="center" font-size="10.5pt" space-before="45pt">
<fo:block><fo:leader leader-length="6.8in" leader-pattern="space"/><fo:page-number/></fo:block>
</fo:block>
</xsl:template>
当我删除
<fo:conditional-page-master-reference master-reference="cover"
page-position="first" />
来自<fo:page-sequence-master master-name="CoverPage">，
FOP引发以下异常：
FOPException：在page-sequence-master“CoverPage”中耗尽的子序列无法解析
关于如何处理这个的任何想法或帮助？
