无法更改XSL-FO中列表项之间的空间

Question

provisional-label-separation属性似乎不会影响间距。我还尝试了margin-*，padding-*，space-before和space-after，但列表项之间的空间仍然不会改变。如何更改列表中列表项之间的垂直空间（如果这会产生影响，我将渲染为PDF）？

<fo:list-block provisional-distance-between-starts="3mm" 
               provisional-label-separation="3mm" 
               space-after="3mm" >

    <fo:list-item>
        <fo:list-item-label end-indent="label-end()">
            <fo:block>&#x2022;</fo:block>
        </fo:list-item-label>
        <fo:list-item-body start-indent="body-start()" font-size="9pt">
            <fo:block>Day care or nanny expenses</fo:block>
        </fo:list-item-body>
    </fo:list-item>

    <fo:list-item>
        <fo:list-item-label end-indent="label-end()">
            <fo:block>&#x2022;</fo:block>
        </fo:list-item-label>
        <fo:list-item-body start-indent="body-start()" font-size="9pt">
            <fo:block>Field trips</fo:block>
        </fo:list-item-body>
    </fo:list-item>

    <fo:list-item>
        <fo:list-item-label end-indent="label-end()">
            <fo:block>&#x2022;</fo:block>
        </fo:list-item-label>
        <fo:list-item-body start-indent="body-start()" font-size="9pt">
            <fo:block>School supplies</fo:block>
        </fo:list-item-body>
    </fo:list-item>

    <fo:list-item>
        <fo:list-item-label end-indent="label-end()">
            <fo:block>&#x2022;</fo:block>
        </fo:list-item-label>
        <fo:list-item-body start-indent="body-start()" font-size="9pt">
            <fo:block>Music lessons and other extracurricular activities</fo:block>
        </fo:list-item-body>
    </fo:list-item>

</fo:list-block>

要更改列表项之间的垂直空间，请在列表项上使用space-after（或者space-before）：

<fo:list-item space-after="5mm">
  <fo:list-item-label end-indent="label-end()">
     <fo:block>&#x2022;</fo:block>
  </fo:list-item-label>
  <fo:list-item-body start-indent="body-start()" font-size="9pt">
       <fo:block>Day care or nanny expenses</fo:block>
  </fo:list-item-body>
</fo:list-item>

provisional-label-separation指定list-item-label的结尾与list-item-body的开头之间的临时距离（即，它是水平距离）。请参阅http://www.w3.org/TR/xsl/#d0e12377。
