I didn't have any trouble using the following WSDL, which is very similar
to yours. If you post your code I can take a look at it...
<types>
<s:schema elementFormDefault="qualified"
targetNamespace="http://tempuri.org/";>
<s:element name="Test">
<s:complexType />
</s:element>
<s:element name="TestResponse">
<s:complexType>
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="TestResult"
type="s0:Composite" />
</s:sequence>
</s:complexType>
</s:element>
<s:complexType name="Composite">
<s:choice>
<s:element name="PO" minOccurs="1" maxOccurs="1" type="s0:PO"/>
<s:element name="Invoice" minOccurs="0" maxOccurs="unbounded"
type="s0:Invoice"/>
</s:choice>
</s:complexType>
<s:complexType name="PO">
<s:sequence>
<s:element minOccurs="1" maxOccurs="1" name="poNumber"
type="s:int" />
</s:sequence>
</s:complexType>
<s:complexType name="Invoice">
<s:sequence>
<s:element minOccurs="1" maxOccurs="1" name="invoiceNumber"
type="s:int" />
</s:sequence>
</s:complexType>
</s:schema>
</types>
