Is it possible in some way, to define an xsd scheme which could validate such xml:

<item_list>
  <item ItemType="SimpleMessage" Caption="Simplest message"/>
  <item ItemType="ComplexMessage" SomeAttr="value">
    <item_data>some text</item_data>
  </item>
</item_list>

Problem is that i havn't find any possibility to define smth like:

  <xsd:element name="Items">
      <xsd:complexType>
        <xsd:choice>
          <xsd:element name="item" type="SimpleMessType"/>
          <xsd:element name="item" type="ComplexMessType"/>
        </xsd:choice>
      </xsd:complexType>
  </xsd:element>

But i need to check, that SimpleMessage has no child elements or additional attrs :(
