RE: ISSUE-104: ComplexTypeChoiceExtension

Too many choices..... The actual base class was a sequence of course: 

<xs:complexType name="ComplexTypeChoiceBase"> 

<xs:sequence> 

<xs:element name="name" type="xs:string"/> 

</xs:sequence> <

/xs:complexType>

Our schemas in the wild trawl has thrown up some examples of this advanced
pattern:

  <xs:element name="complexTypeChoiceExtension"
type="ex:ComplexTypeChoiceExtension"/>

  <xs:complexType name="ComplexTypeChoiceBase">
            <xs:choice>
               <xs:element name="name" type="xs:string"/>
            </xs:choice>
         </xs:complexType>

  <xs:complexType name="ComplexTypeChoiceExtension">
            <xs:complexContent>
               <xs:extension base="ex:ComplexTypeChoiceBase">
                  <xs:choice>
                     <xs:element name="surname1" type="xs:string"/>
                     <xs:element name="surname2" type="xs:string"/>
                     <xs:element name="surname3" type="xs:string"/>
                  </xs:choice>
               </xs:extension>
            </xs:complexContent>
         </xs:complexType>
