title: Why does region-start begin at the top of the page when a region-before is present?
body: <p>According to the <a href="http://www.w3.org/TR/2001/REC-xsl-20011015/slice6.html#fo_simple-page-master" rel="nofollow">Formatting Object documentation</a>  the region-start (the region to the left of the body) spans <strong>between</strong> region-before (the header) and region-after (the footer), but when I generate a PDF with <a href="http://xmlgraphics.apache.org/fop/" rel="nofollow">FOP</a> (v1.1) region-start will begin at the <strong>top of the page</strong> and will push the region-before to the right.</p>
  
  <p>So, is there any attribute or anything that makes the generator to place the region-start to begin <strong>below</strong> region-before?</p>
  
  <p>Here is some example code:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="ISO-8859-1"?&gt;
  &lt;xsl:stylesheet version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:fo="http://www.w3.org/1999/XSL/Format"&gt;
  
  &lt;xsl:template match="/"&gt;
      &lt;fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format"&gt;
          &lt;fo:layout-master-set&gt;
              &lt;fo:simple-page-master master-name="A4-cover"
                  page-width="210mm" page-height="297mm" margin="12mm"&gt;
                  &lt;fo:region-body margin-top="60mm" margin-left="85mm" /&gt;
                  &lt;fo:region-before extent="55mm" /&gt;
                  &lt;fo:region-start extent="80mm" /&gt;
              &lt;/fo:simple-page-master&gt;
          &lt;/fo:layout-master-set&gt;
  
          &lt;fo:page-sequence master-reference="A4-cover"&gt;
              &lt;fo:static-content flow-name="xsl-region-before"&gt;
                  &lt;fo:block background-color="blue"&gt;
                      Before area
                  &lt;/fo:block&gt;
              &lt;/fo:static-content&gt;
  
              &lt;fo:static-content flow-name="xsl-region-start"&gt;
                  &lt;fo:block background-color="red"&gt;
                      Start area
                  &lt;/fo:block&gt;
              &lt;/fo:static-content&gt;
  
              &lt;fo:flow flow-name="xsl-region-body"&gt;
                  &lt;fo:block background-color="green"&gt;
                      Body area
                  &lt;/fo:block&gt;
              &lt;/fo:flow&gt;
          &lt;/fo:page-sequence&gt;
      &lt;/fo:root&gt;
  &lt;/xsl:template&gt;
  &lt;/xsl:stylesheet&gt;
