Try the following XUpdate on attached XML document.

<xupdate:modifications version="1.0"
xmlns:xupdate="http://www.xmldb.org/xupdate";>
   <xupdate:append select="//class" >
         <xupdate:attribute name="order">777</xupdate:attribute>
   </xupdate:append>
</xupdate:modifications>

When I run it, it causes "internal server error" response and raises the
following trace:
