当存在名称空间前缀时,无法通过Id属性对元素进行签名:

void Main()
{
    var doc = new XmlDocument();
    doc.LoadXml("<root xmlns:u=\"myuri\"><test u:Id=\"_0\">Zebra</test></root>");

    SignedXml signedXml = new SignedXml(doc);
    signedXml.SigningKey = new RSACryptoServiceProvider();

    Reference reference = new Reference("#_0");
    signedXml.AddReference(reference);

    signedXml.ComputeSignature();
}

ComputeSignature() 这里会出现'格式错误的参考元素'应该怎么做？
