Trading API GetUserPreferences Schema definition is missing minOccurs="0" on 4 optional fields and 1 deprecated field, causing the fields to be required:
optional field:
<xs:element name="ShowBidderNoticePreferences" type="xs:boolean">
<xs:element name="ShowCombinedPaymentPreferences" type="xs:boolean">
<xs:element name="ShowSellerPaymentPreferences" type="xs:boolean">
<xs:element name="ShowSellerProfilePreferences" type="xs:boolean">
deprecated field:
<xs:element name="ShowCrossPromotionPreferences" type="xs:boolean">
All need minOccurs="0" tag added to the end to avoid schema errors when they aren't included.
