The MerchantItemAttributes response group returns merchant-specific information about a merchant's items for sale. The XML element tags returned by MerchantItemAttributes are the same as those returned by ItemAttributes. The values, however, returned by the response groups are mutually exclusive. The number of elements returned by MerchantItemAttributes is typically fewer than those returned by ItemAttributes because merchants typically change only a small subset of attributes returned by ItemAttributes.
MerchantItemAttributes is valid only for the following operations: ItemLookup and ItemSearch and only when a MerchantId is specified. MerchantId, however, cannot equal "All."
