以下のコードは、XMLをマーシャリングするときに奇妙なことにxmlns属性をルート要素に追加します。私が読んだことから、xmlns属性は明示的に設定すべきではありません。goxmldsigを使用してXMLをマーシャリングした後に無効なxmlns値
org.xml.sax.SAXParseException: The prefix "xml" cannot be bound to any namespace other than its usual namespace; neither can the namespace for "xml" be bound to any prefix other than "xml".
が有効なのxmlnsは、私が使用できる属性値またはAMです：
<?xml version="1.0" encoding="UTF-8"?>
<ExampleElement xmlns="http://www.w3.org/XML/1998/namespace" ID="id1234">
...
は、私は次のエラーが表示さXMLSecToolとXML署名を検証しようとすると：しかし、結果のXMLは、xmlns属性が含ま私はライブラリを間違って使用していますか？
