XSD架構參考完整性xs：keyref

我有一個xsd命名的Event，其中包含AccountStructureItem和EventItem類型的兩個列表（「AccountStructures」和「Events」）。有一個屬性：AccountStructureItem中的SourceId被定義爲唯一和密鑰。 EventItem類型還有一個SourceId屬性，它是對AccountStructureItem的SourceId的引用。XSD架構參考完整性xs：keyref

我宣佈AccountStructureItem's ID如下：

<xs:unique name="accounts_unique"> 
<xs:selector xpath="AccountStructureItem"/> 
<xs:field xpath="SourceId"/> 
</xs:unique> 

<xs:key name="accounts_key"> 
<xs:selector xpath="AccountStructureItem"/> 
<xs:field xpath="SourceId"/> 
</xs:key>

的關係是一對多的，可以有很多EventItem's指同一AccountStructureItem's的SourceID。因此EventItem的關鍵是另一個屬性。

我的問題：嘗試使用下面的xs：keyref爲accountstructure的accounts_key創建密鑰引用約束時出錯。

<xs:keyref name="events_constraint" refer="accounts_key"> 
<xs:selector xpath="AccountStructureItem"/> 
<xs:field xpath="SourceId"/> 
</xs:keyref>

在驗證下面的錯誤消息如下：「該keyref活動找不到簡稱鍵或在範圍上獨特的」

請參考下面提供的完整的XSD和測試XML文件：

我自己拿到了解決方案。問題在於我在元素列表中聲明瞭鍵和引用。我現在將這個關鍵字，唯一關鍵字和ref參數的聲明移到了兩個列表之外，並使用「list/item」xpath來訪問它們。就像這樣：

<xs:selector xpath="AccountStructures/AccountStructureItem"/> 
    <xs:field xpath="SourceId"/> 
</xs:unique> 

<xs:key name="accounts_key" id="accounts_key_id"> 
    <xs:selector xpath="AccountStructures/AccountStructureItem"/> 
    <xs:field xpath="SourceId"/> 
</xs:key> 

<xs:unique name="events_unique"> 
    <xs:selector xpath="Events/EventItem"/> 
    <xs:field xpath="SourceEventId"/> 
</xs:unique> 

<xs:key name="events_key"> 
    <xs:selector xpath="Events/EventItem"/> 
    <xs:field xpath="SourceEventId"/> 
</xs:key> 

<xs:keyref name="events_constraint" refer="accounts_key"> 
    <xs:selector xpath="Events/EventItem"/> 
    <xs:field xpath="SourceId"/> 
</xs:keyref>
