c# - XML 验证成功但应该失败

Question

我将 XML 序列化与 XmlSerializer 一起使用。在阅读文档之前，我会尝试根据 XSD 对其进行验证，以确定要选择的正确版本。

验证成功 - 但应该失败！

我的验证码是：

var schemaSet = new XmlSchemaSet();
schemaSet.Add(null, XmlReader.Create(new StringReader(xsd)));

var document = XDocument.Load(new StringReader(xml));

var hasErrors = false;
document.Validate(schemaSet, (s, e) => hasErrors = true);

Console.WriteLine("Document has erros: {0}", hasErrors);
if (hasErrors == false)
    Console.WriteLine("!!!! THIS DOCUMENT IS VALID !!!!");

输出是：

Document has erros: False
!!!! THIS DOCUMENT IS VALID !!!!

演示

此外， MSDN建议的代码也将成功验证（也包含在 DEMO 中 - 已注释掉）：

var settings = new XmlReaderSettings();
settings.Schemas.Add(null, XmlReader.Create(new StringReader(xsd)));
settings.ValidationType = ValidationType.Schema;
settings.ValidationFlags = XmlSchemaValidationFlags.ReportValidationWarnings;
settings.Schemas.Compile();

var contentReader = XmlReader.Create(new StringReader(xml), settings);
var document = new XmlDocument();
document.Load(contentReader);

var hasErrors = false;
document.Validate((s, e) => hasErrors = true);
Console.WriteLine("Document has erros: {0}", hasErrors);
if (hasErrors == false)
    Console.WriteLine("!!!! THIS DOCUMENT IS VALID !!!!");

用于测试的 XSD 被剥离为仅包含一个属性的一种类型：

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema
    targetNamespace="http://www.xxx.de/V1_1/LightningChartConfiguration"
    elementFormDefault="qualified" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.xxx.de/V1_1/LightningChartConfiguration" xmlns:tns="http://www.xxx.de/V1/Common" xmlns:pref="http://www.xxx.de/V1/Triggers">

    <xsd:element name="root" type="LightningChartConfigurationRoot_1_1"></xsd:element>

    <xsd:complexType name="LightningChartConfigurationRoot_1_1">
        <xsd:sequence>
            <xsd:element name="Version" maxOccurs="1" minOccurs="1">
                <xsd:simpleType>
                    <xsd:restriction base="xsd:string">
                        <xsd:enumeration value="V1_1"></xsd:enumeration>
                    </xsd:restriction>
                </xsd:simpleType>
            </xsd:element>
        </xsd:sequence>
    </xsd:complexType>
</xsd:schema>

要测试的 XML 是：

XML 显然太大了，并且包含更多 XSD 允许的标签。然而，XSD 验证成功，没有任何错误。XSD 中唯一允许的标记是它在 XML 中是version有限制的。V1_1V1_0

我创建了一个重现这种有线行为的演示。

我在这里想念什么？我需要做什么才能使 XSD 验证按预期工作？

如果您将 XSD 和 XML 复制到例如此页面，则验证将按预期失败。
