XSD xs：選擇不應該允許空選擇

我的XSD存在問題。我的XSD包含一個xs:choice以實現選擇這些類型中的一個的選項。不應該允許選擇類型（或空值）！XSD xs：選擇不應該允許空選擇

<xs:complexType name="TypeAndValue"> 
<xs:choice minOccurs="1"> 
    <xs:element minOccurs="1" name="SimpleType" nillable="false" type="SimpleDataTypeAndValue" /> 
    <xs:element minOccurs="1" name="ArrayType" nillable="false" type="ArrayTypeAndValue" /> 
    <xs:element minOccurs="1" name="ListType" nillable="false" type="ListTypeAndValue" /> 
    <xs:element minOccurs="1" name="ClassType" nillable="false" type="IdentifierTypeAndValue" /> 
</xs:choice>

我創建從XSD通過XSD.EXE一個cs文件。這工作正常，沒有錯誤。但是，如果我嘗試一個XML文件中像這樣的XML將被接受：

<?xml version="1.0"?> 
<Block xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> 
    <Class Identifier="Test"> 
     <Declaration Identifier="List"> 
     <TypeAndValue> 
     </TypeAndValue> 
     </Declaration> 
    </Class> 
</Block>

我試過和nillable="false"在選擇和元素，但架構接受空TypeAndValue塊。

難道是我需要修改cs文件嗎？

編輯：下面是完整的XSD：
