参考架构包含当前文档的错误？

Question

当我配置log4net时，它会发生：

the reference schema contains error from current document.
The foundation connect has been closed,recieving error!

这段代码：

<log4net xsi:noNamespaceSchemaLocation="http://csharptest.net/downloads/schema/log4net.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
        <appender name="InfoFileAppender" type="log4net.Appender.RollingFileAppender">
            <file value="D:/a.txt" />
            <appendToFile value="true" />
            <param name="DatePattern" value="yyyyMMdd&quot;.txt&quot;" />
            <rollingStyle value="Date" />
            <maxSizeRollBackups value="100" />
            <datePattern value="yyyy-MM-dd'.log'"/>
            <maximumFileSize value="1024KB" />
            <staticLogFileName value="false" />
            <encoding value="utf-8"/>           
            <filter type="log4net.Filter.LevelRangeFilter">    <log4net xsi:noNamespaceSchemaLocation="http://csharptest.net/downloads/schema/log4net.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
        <appender name="InfoFileAppender" type="log4net.Appender.RollingFileAppender">
            <file value="D:/a.txt" />
            <appendToFile value="true" />
            <param name="DatePattern" value="yyyyMMdd&quot;.txt&quot;" />
            <rollingStyle value="Date" />
            <maxSizeRollBackups value="100" />
            <datePattern value="yyyy-MM-dd'.log'"/>
            <maximumFileSize value="1024KB" />
            <staticLogFileName value="false" />
            <encoding value="utf-8"/>           
            <filter type="log4net.Filter.LevelRangeFilter">

xsi中的

：noNamespaceSchemaLocation =“http://csharptest.net/downloads/schema/log4net.xsd”，出了什么问题？
