bad type generation for xs:choice + maxOccurs="unbounded"

[wthorp]

This appears to be working in the fixtures, but not in my use case.

From Sono's WSDL...

<xs:complexType name="mediaList">
...
  <xs:choice minOccurs="0" maxOccurs="unbounded">
    <xs:element name="mediaCollection" type="tns:mediaCollection"/>
    <xs:element name="mediaMetadata" type="tns:mediaMetadata"/>
 </xs:choice>
</xs:complexType>

generates

type MediaList struct {
...
  MediaCollection *MediaCollection `xml:"mediaCollection,omitempty" json:"mediaCollection,omitempty"`
  MediaMetadata *MediaMetadata `xml:"mediaMetadata,omitempty" json:"mediaMetadata,omitempty"`
}
