具有特定子元素的XSD必需元素(具有不同类型的多个定义)

所有,我有一个XML文档,我无法控制,我需要创建一个xsd来验证。 XML文档有多种事务类型,其中一些需要特定次数,有些则不需要。父元素只是< transaction>,子元素可以是< ControlTransaction>或者< RetailTransaction>。问题是我需要一个< transaction>以< ControlTransaction>存在使用< ReasonCode>值为“Register Open”的元素和值为“Register Close”的另一个元素如下:

<?xml version="1.0" encoding="UTF-8"?>
<RegisterDay xmlns:xs="http://www.w3.org/2001/XMLSchema" 
    xmlns:cp="urn:register"> 

<Transaction>
    <SequenceNumber>1</SequenceNumber>
    <ControlTransaction>
        <ReasonCode>Register Open</ReasonCode>
    </ControlTransaction>
</Transaction>

<Transaction>
    <SequenceNumber>2</SequenceNumber>
    <RetailTransaction>
        ...stuff..
        <Total>9.99</Total>
    </RetailTransaction>
</Transaction>

<Transaction>
    <SequenceNumber>3</SequenceNumber>
    <ControlTransaction>
        <ReasonCode>Register Close</ReasonCode>
    </ControlTransaction>
</Transaction>

</RegisterDay>

我最好的尝试是在我的架构中使用类型,但得到“具有相同名称和相同范围的元素必须具有相同的类型”。我不知道怎么解决这个问题。

有没有人碰到这个和/或有任何建议?我很难过。

也许是枚举?
