使用jdom如何为XML添加“如此”名称空间

MessageQueueCommand.xml
------------------------------------------------------------------------------------------------------
<?xml version="1.0" encoding="UTF-8" ?>

上面的MessageQueueCommand.xml是需用jdom生成的xml文件。现在这个XML文件除了一个地方（红色字体）我不会添加，其他的都解决了。问题也正是此，像红色字体的名称空间使用jdom该如何添加呢？

备注：
它是一个本地的xsd文件，用来验证生成的xml文件的有效性。
