body: <p>I'm running an xslt transformation in OSB. It invokes the current-dateTime method as follows:           </p>
  
  <pre><code>&lt;db:lastupdate&gt;
      &lt;xsl:value-of select="fn:current-dateTime()"/&gt;
  &lt;/db:lastupdate&gt;
  </code></pre>
  
  <p>It returns the following error:</p>
