title: Antenna House XSL-FO Extensions not working?
body: <p>Any attempt to use Antenna House's xsl-fo extensions by pointing to their namespace (which gives a "page not found" btw) results in an error:</p>
  
  <blockquote>
    <p>The element 'root' in namespace 'http://www.w3.org/1999/XSL/Format' has invalid child element 'document-info' in namespace 'http://www.antennahouse.com/names/XSL/Extensions'. List of possible elements expected: 'layout-master-set' in namespace 'http://www.w3.org/1999/XSL/Format'.</p>
  </blockquote>
  
  <p>It appears that there's some type of namespace referencing issue where the elements in the xsl-fo namespace don't recognize that the extension elements are valid child elements?</p>
  
  <p>Code looks like such:</p>
  
  <pre><code>&lt;xsl:stylesheet version='1.0'
       xmlns:xsl='http://www.w3.org/1999/XSL/Transform'
       xmlns:axf='http://www.antennahouse.com/names/XSL/Extensions'&gt;
      &lt;xsl:template match='/root'&gt;
          &lt;fo:root xmlns:fo='http://www.w3.org/1999/XSL/Format' xmlns:axf='http://www.antennahouse.com/names/XSL/Extensions'&gt;
              &lt;axf:document-info name='title' value='value' /&gt;
          &lt;/fo:root&gt;
      &lt;/xsl:template&gt;
  &lt;/xsl:stylesheet&gt;
  </code></pre>
  
  <p>Funny that they have an example listed on their website that looks exactly the same here:  <a href="http://www.antennahouse.com/xslfo/axf4-extension.htm#axf.document-info" rel="nofollow">http://www.antennahouse.com/xslfo/axf4-extension.htm#axf.document-info</a></p>
  
  <p>Unfortunately it doesn't seem to be working with v4.3 of their xsl formatter.</p>
