WDL types and element definition issue

[Gaellle]

Hi all,

I am facing an issue while defining my WSDL, I perhaps try to do someting that is not possible, but since I need it I need your help !

I need to declare an element of a complexType declared in the same WSDL.
A simple example below, of a complexType cake which should be in format 'cakeFormat' but cannot since cakeFormat is declared as an element :

<wsdl:definitions ...>
  <wsdl:types>
    <xsd:schema ...>
      <xsd:element name="cakeFormat">
        <xsd:complexType>
          <xsd:sequence>
            <xsd:element name="flavour" type="xsd:string" nillable="false"/>
            <xsd:element name="name" type="xsd:string" nillable="false"/>
          </xsd:sequence>
        </xsd:complexType>
      </xsd:element>
      <xsd:element name="checkMeal">
        <xsd:complexType>
          <xsd:sequence>
            <xsd:element name="meat" type="xsd:string" nillable="false"/>
            <xsd:element name="pie" type="tns:cakeFormat" nillable="false"/>
          </xsd:sequence>
        </xsd:complexType>
      </xsd:element>
      <xsd:element name="checkMealResponse">
           <xsd:element name="mealMark" type="xsd:int" nillable="false"/>
      </xsd:element>
    </xsd:schema>
  </wsdl:types>

My WSDL cannot be validated : how can I declare in a complexType definition, an element of another complexType declared just above ?

Thanks and have a nice day !
