            <h:div class="description" xmlns:h="http://www.w3.org/1999/xhtml">A documentation container similar to <h:tt>annotation</h:tt> in XML Schema. At present this is experimental and designed to be used for dictionaries, units, etc. One approach is to convert these into XML Schemas when the <h:tt>documentation</h:tt> and <h:tt>appinfo</h:tt> children will emerge in their correct position in the derived schema.
        <h:p>It is possible that this may develop as a useful tool for annotating components
        of complex objects such as molecules. </h:p>
