    <para>
        <classname>Zend_Ldap_Node</classname> includes the magic propery accessors
        <methodname>__set()</methodname>, <methodname>__get()</methodname>,
        <methodname>__unset()</methodname> and <methodname>__isset()</methodname> to access the
        attributes by their name. They proxy to
        <methodname>Zend_Ldap_Node::setAttribute()</methodname>,
        <methodname>Zend_Ldap_Node::getAttribute()</methodname>,
        <methodname>Zend_Ldap_Node::deleteAttribute()</methodname> and
        <methodname>Zend_Ldap_Node::existsAttribute()</methodname> respectively. Furthermore the
        class implements <code>ArrayAccess</code> for array-style-access to the attributes.
        <classname>Zend_Ldap_Node</classname> also implements <code>Iterator</code> and
        <code>RecursiveIterato</code> to allow for recursive tree-traversal.
