I have the following elements in my schema:

<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified"
xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:complexType name="optimizeModelBase">
    <xs:attribute name="name" type="xs:string"/>
  </xs:complexType>

  <xs:complexType name="riskModel">
    <xs:complexContent>
      <xs:extension base="optimizeModelBase">
        <xs:attribute name="type" type="xs:string" use="required"/>        
      </xs:extension>      
    </xs:complexContent>
  </xs:complexType>

  <xs:complexType name="fullCovariance">
    <xs:complexContent>
      <xs:extension base="optimizeModelBase">
        <xs:attribute name="fromDate" type="xs:date" use="required"/>
        <xs:attribute name="toDate" type="xs:date" use="required"/>
        <xs:attribute name="windowSize" type="xs:int" use="required"/>
      </xs:extension>
    </xs:complexContent>    
  </xs:complexType>

In my main schema body, I use a element to specify a 1-of situation:

<xs:choice id="RiskModelParameter">
  <xs:element name="RiskModel" type="riskModel"/>
  <xs:element name="FullCovariance" type="fullCovariance"/>
</xs:choice>

When I run xsd.exe, the resulting code is:

    [System.Xml.Serialization.XmlElementAttribute("FullCovariance",
    typeof(fullCovariance))]
    [System.Xml.Serialization.XmlElementAttribute("RiskModel", 
    typeof(riskModel))]
    public optimizeModelBase Item 
    {
        get 
        {
           return this.itemField;
        } 
        set 
        {
            this.itemField = value;
        }
    }

The issue is that the element's ID tag is being ignored, and xsd.exe is arbitrarily naming the property "Item". I have to admit, it's not a big issue, but it's starting to annoy me. What makes this extra annoying is that if I have additional elements at the same level, xsd.exe binds them as "Item1", "Item2", etc.

Does anyone know if it's possible to not have xsd.exe name my choice elements as "Item", and instead be able to put in my own property names?
