title: XSL-FO - Empty block elements
body: <p>I have a quite simple template:</p>
  
  <pre><code>&lt;xsl:template match="p"&gt;
      &lt;fo:block&gt;
          &lt;xsl:apply-templates/&gt;
      &lt;/fo:block&gt;
  &lt;/xsl:template&gt;
  </code></pre>
  
  <p>How do I tell FO to keep empty lines even if the block is empty.</p>
