Type defining the item container that is returned in getUserCases and getEBPCaseDetail calls. The item container identifies the listing site, the item listing involved in the case, and the transaction details.
Since there can be multiple cases returned with the getUserCases call, the item container can appear more than once in the getUserCases request. getUserCases only returns the itemId, itemTitle, and transactionId fields.
The getEBPCaseDetail call returns the details for one case, hence only one item container. All child fields are returned.
