XSL:FO 只保留第一页的页眉

Question

我无法仅在第一页保留 "region-before"。看我的代码：

    <fo:layout-master-set>
            <fo:simple-page-master master-name="first" margin-right="0.5cm" margin-left="0.5cm" margin-bottom="0.5cm" margin-top="0.75cm" page-width="21cm" page-height="29.7cm">

                <fo:region-body region-name="xsl-region-body" margin-top="{$extra-body-margin-top+15.6-$header-margin}cm" margin-bottom="3.5cm" />
                <fo:region-before region-name="xsl-region-before"  extent="17cm" overflow="hidden" />
                <fo:region-after region-name="xsl-region-after" extent="2.8cm" overflow="hidden" />
            </fo:simple-page-master>
            <fo:page-sequence-master master-name="psmA">
                <fo:repeatable-page-master-alternatives>
                    <fo:conditional-page-master-reference master-reference="first" page-position="any" />
                </fo:repeatable-page-master-alternatives>
            </fo:page-sequence-master>

    </fo:layout-master-set>

如果我更改 page-position="first" 并且我的 region-body 超出了第一页，我就会出错。我的想法是只在第一页上保留 region-before，但 region-body 和 region-footer 跟在下一页之后。有没有简单的代码可以玩我的代码？

设置没有 fo:region-before 的第二个 fo:simple-page-master。
添加第二个 fo:conditional-page-master-reference，这样 first 页面母版仅用于第一页（使用 page-position="first"），其他页面母版用于其余页面（使用page-position="any").

这是可行的，因为格式化程序使用第一个替代方案，其所有条件都为真（参见 https://www.w3.org/TR/xsl11/#fo_repeatable-page-master-alternatives）。这也是为什么将带 page-position="any" 的那个放在最后，因为该条件始终为真。

<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
  <fo:layout-master-set>
    <fo:simple-page-master master-name="first" margin-right="0.5cm" margin-left="0.5cm" margin-bottom="0.5cm" margin-top="0.75cm" page-width="21cm" page-height="29.7cm">

      <fo:region-body region-name="xsl-region-body" margin-top="1cm" margin-bottom="3.5cm" />
      <fo:region-before region-name="xsl-region-before"  extent="17cm" overflow="hidden" />
      <fo:region-after region-name="xsl-region-after" extent="2.8cm" overflow="hidden" />
    </fo:simple-page-master>
    <fo:simple-page-master master-name="rest" margin-right="0.5cm" margin-left="0.5cm" margin-bottom="0.5cm" margin-top="0.75cm" page-width="21cm" page-height="29.7cm">

      <fo:region-body region-name="xsl-region-body" margin-top="1cm" margin-bottom="3.5cm" />
    </fo:simple-page-master>
    <fo:page-sequence-master master-name="psmA">
      <fo:repeatable-page-master-alternatives>
        <fo:conditional-page-master-reference master-reference="first" page-position="first" />
        <fo:conditional-page-master-reference master-reference="rest" page-position="any" />
      </fo:repeatable-page-master-alternatives>
    </fo:page-sequence-master>

  </fo:layout-master-set>

  <fo:page-sequence master-reference="psmA">
    <fo:static-content flow-name="xsl-region-before">
      <fo:block>before</fo:block>
    </fo:static-content>
    <fo:flow flow-name="xsl-region-body" font-size="12pt" line-height="11pt">
      <fo:block>content</fo:block>
      <fo:block break-before="page">more content</fo:block>
    </fo:flow>
  </fo:page-sequence>
</fo:root>
