问使用<SELECT>作为配置向Zend_Form描述XML元素的正确语法是什么？

EN

$formConfig = new Zend_Config_Xml('/path/to/form.xml');
$form = new Zend_Form($formConfig);
$form->getElement('myselect')->setMultiOptions($arrayOfOptions);

<?xml version="1.0" encoding="UTF-8"?>
<form>
    <user>
        <example>
            <name>mysampleform</name>
        <method>post</method>
        <elements>
        <myselect>
                <type>select</type>
                <name>myselect</name>
                <multioptions> <!-- custom tag -->
                    <option value="First">1</option>
                    <option value="Second">2</option>
                    <option value="Third">3</option>
                </multioptions>
                <options>
                    <label>Choose an option:</label>                        
                    <required>true</required>
                </options>
            </myselect>

            </options>
            </submit>   
        </elements>    
    </example>
</user>

$formConfig = new Zend_Config_Xml('/path/to/form.xml');
$form = new Zend_Form($formConfig);
$form->getElement('myselect')->setMultiOptions(
    $formConfig->user->example->elements->myselect->multioptions->toArray()
);
