XSD 특정 하위 요소가있는 필수 요소

Question

모두, 유효성을 검사 할 xsd를 작성해야하는 XML 문서가 있습니다. XML 문서에는 여러 트랜잭션 유형이 있으며 그 중 일부는 특정 횟수가 필요하고 일부는 필요하지 않습니다. 상위 요소는 단순히 < 트랜잭션 >이고 하위 요소는 <ControlTransaction > 또는 <RetailTransaction> 일 수 있습니다.

<?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> 

: 문제는 내가 > 다음과 같이 "등록 닫기"의 값으로 "등록 열기"의 값과 다른를 갖는 <ReasonCode> 요소와 <ControlTransaction> 존재하는 < 거래를 필요로 할 필요가 있다는 것입니다

내 최선의 시도는 내 스키마에서 유형을 사용하는 것이지만 "같은 이름과 같은 범위를 가진 요소는 같은 유형이어야합니다."라는 메시지가 나타납니다. 이 문제를 해결하는 방법을 모르겠습니다.

아무에게도이 문제가 있거나 의견이 있으십니까? 나는 꽤 많이 곤란하다.
