The return element contains the data returned by the Discover and Execute methods. Typically, the return element contains a single root element that contains either the data returned by a successful Discover or Execute method call or an XML for Analysis (XMLA) exception returned by an unsuccessful method call. If the Execute method contains a Batch command that performs multiple operations, the return element contains a results element which, in turn, contains one root element for each command executed successfully or unsuccessfully by the Batch command.
