> We have a WSDL file that contains a schema similar to the following snippet:
>                       <xsd:complexType name="dateType">
>                               <xsd:choice>
>                                       <xsd:sequence>
>                                               <xsd:element name="notBefore"
>                                                       
> type="tns:DateOrDateTime" minOccurs="1" maxOccurs="1">
>                                               </xsd:element>
>                                               <xsd:element name="notAfter"
>                                                       
> type="tns:DateOrDateTime" minOccurs="0" maxOccurs="1">
>                                               </xsd:element>
>                                       </xsd:sequence>
>                                       <xsd:element name="notAfter"
>                                               type="tns:DateOrDateTime" 
> minOccurs="1" maxOccurs="1">
>                                       </xsd:element>
>                               </xsd:choice>
>                       </xsd:complexType>
>                       <xsd:simpleType name="DateOrDateTime">
>                               <xsd:union memberTypes="xsd:dateTime 
> xsd:date"></xsd:union>
>                       </xsd:simpleType>
> The intention is that an element of type DateType has two optional elements 
> notBefore and notAfter, but at least one of these elements has to be there.
> However, the generated DateType.parse(javax.xml.stream.XMLStreamReader 
> reader) enters an infinite loop when both elements are provided. The problem 
> is that it correctly evaluates the type attribute in the notBefore element in 
> DateTypeSequence_type0.parse(javax.xml.stream.XMLStreamReader reader), but 
> fails to find the Java class this type is bound to.
> The generated code exhibits another problem as well, I think: When parsing an 
> element of Type DateOrDateTime, it expects a type attribut. But if there is 
> no type attribute, then it should try the various union types in the order of 
> their declaration, cf. section 2.5.1.3 of 
> <URL:http://www.w3.org/TR/xmlschema-2/#atomic-vs-list>.
