将内容适配到PDF中的单个页面

我正在使用xslt和fo构建PDF。我的要求是PDF的内容仅限于一页

在某些情况下，PDF将分为两页。我必须避免那样。以下是主设置的代码

<fo:layout-master-set>

            <fo:simple-page-master master-name="StandardPage" page-height="250mm" page-width="297mm">
                <fo:region-body margin-bottom="20mm" margin-top="12mm" margin-left="14mm" margin-right="6mm"/>
                <fo:region-before region-name="headerContent" extent="12mm"/>
                <fo:region-after region-name="footer" extent="20mm" precedence="true"/>
                <fo:region-start region-name="leftBorder" extent="14mm"/>
                <fo:region-end region-name="rightBorder" extent="6mm"/>
            </fo:simple-page-master>
        </fo:layout-master-set>
        <fo:page-sequence master-reference="StandardPage">
            <fo:flow flow-name="xsl-region-body">

下面是xsl中的内容。我们有18种选择，同样的选择重复了18次

<fo:table-row>
<fo:table-cell number-columns-spanned="2">
    <fo:block font-size="18pt" font-family="ABC" font-weight="bold" text-align="left" line-height="14pt">
        <fo:list-block>
            <fo:list-item>
                <fo:list-item-label>
                    <fo:block>&#x2022;</fo:block>
                </fo:list-item-label>
                <fo:list-item-body start-indent="4mm">
                    <fo:block>
                    <xsl:variable name="opt18" select="string(//void[@property='optionListEntryEighteen']/string/text())"/>
                        <xsl:value-of select="$opt18"/>
                    </fo:block>
                </fo:list-item-body>
            </fo:list-item>
        </fo:list-block>
    </fo:block>
</fo:table-cell>

有时所有18个选项都适合一个页面，有时16个选项适合一个页面，接下来的两个选项将移动到下一页

我的要求是在一个页面中设置选项如果在一个页面中设置了10个选项，则在该页面中显示10个选项，而不显示其他选项

如何实现这一点？

我没有信心，但是使用fo:single page master reference&fo:block container和@height和@overflow=hidden如何？这是通过FOP测试的
