带有xsd:any的架构-XmlReader验证错误

尝试使用xsd:any元素时,我的模式中的类型有问题。 在验证期间,我遇到验证异常:“MerchanceAccount”元素未声明。

其思想是能够在extendedproperties元素中指定任何属性和值。 请告诉我做错了什么。

架构的一部分

...
<xsd:complexType name="ExtendedPropertiesType">
    <xsd:sequence>
      <xsd:any minOccurs="0" maxOccurs="unbounded" />
    </xsd:sequence>
</xsd:complexType>

<xsd:complexType name="ProcessorInstanceType">
  <xsd:all>
    <xsd:element name="Id" type="xsd:string" />
    <xsd:element name="Descriptor" type="xsd:string" />
    <xsd:element minOccurs="0" name="ExtendedProperties" type="ExtendedPropertiesType" />
  </xsd:all>
  <xsd:attribute name="name" type="xsd:string" />
</xsd:complexType>
...

XML文件的一部分:

...
<ProcessorInstance name="aaaa">
  <Id>37fc527b-2845-43d0-99ca-ac1ff6f0ed86</Id>
  <Descriptor>Test</Descriptor>

  <ExtendedProperties>
    <MerchantAccount>1111</MerchantAccount>
  </ExtendedProperties>
</ProcessorInstance>
...

验证代码:

private static XmlDocument loadConfigurationXml(FileInfo configFile)
    {
        //load schema
        var sr = new StringReader(Schemas.ConfigurationSchema);
        var schema = XmlSchema.Read(sr, (o, ea) => { throw ea.Exception; });
        //validate against the schema
        var schemas = new XmlSchemaSet();
        schemas.Add(schema);
        var readerSettings = new XmlReaderSettings
        {
            ValidationType = ValidationType.Schema, 
            ValidationFlags = XmlSchemaValidationFlags.ReportValidationWarnings,
            Schemas = schemas,
        };
        readerSettings.ValidationEventHandler += (o, ea)=>
        {
            throw new PaynetValidationException(
                string.Format("Invalid configuration file, see schema for details: {0}", 
                              ea.Message), 
                ea.Exception);
        };
        var reader = XmlReader.Create(configFile.FullName, readerSettings);
        //parse and validate config file
        while (reader.Read()){}

        var ret = new XmlDocument();
        if (configFile.Length != 0)
            ret.Load(configFile.FullName);

        return ret;
    }
