Java XSL Transformation抱怨绑定前缀到命名空间

Question

我尝试使用XSL和javax.xml.transform.Transformer转换来自Garmin Watch的TCX文件的XML文档。这是文件（缩短）：

我使用javax.xml.transform.Transformer执行此任务并得到一个奇怪的错误。变压器给我以下错误信息：

  

元素“xmlns：xsi”不能将“xmlns”作为其前缀。

它属于以下行：

<Creator xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="Device_t">

从我的角度来看，这条线是有效的。给定的命名空间仅绑定到前缀xsi。是否有必要将Transformer配置为正确检测它，还是需要在xsl文件中指定某些内容？
