错误：在XML架构集合中多次指定了元素或属性类型

我的XML模式集合有什么问题：x，它抛出了错误

下面是一个XML示例，我为其编写了一个XML模式集合：

<ReviewRules xmlns="urn:goldleaf-schema:ReviewRules" version="1.0">
    <Name>Never Apply Review Rule</Name>
    <ReviewBasis>Never</ReviewBasis>
    <DefaultReviewerComment>Review not required as per rule.</DefaultReviewerComment>
    <PayLimit AutoReject="True">20000</PayLimit>
    <UserLimit AutoReject="True">25000</UserLimit>
    <DailyTotalLimit AutoReject="True">50000</DailyTotalLimit>
    <TotalLimit AutoReject="True">75000</TotalLimit>
</ReviewRules>

如果对审阅规则有任何架构更改，则版本属性应该是固定的并增加。

此XSD无法验证XML，并给出错误：

多次指定的元素或属性类型。位置：'/:schema[1]/:complexType[1]/:sequence[1]/:element[4]/*：complexType[1]'。

您可能会发现Saxon的错误消息更有用：

Error at xsd:element on line 16 column 85 of test.xsd:

基本上，您可以使用type属性或complexType子元素指定元素的类型，但不能同时使用这两个元素-这没有意义。

好的，我同意，但元素的类型as属性会给出相同的错误。也尝试过这个

那是另一个错误。不能将xs:attribute作为xs:element的子级。不要试着猜测XSD语法——猜测永远不会正确。
