INSERT from OPENXML inserts NULL rows

I have a piece of code which shreds XML files to table values. The problem is that for every order response I insert a few rows with all NULL columns are inserted too. How can I fix it?

EXEC sys.sp_xml_preparedocument @DocHandle OUTPUT
    ,@XmlDocument;

INSERT INTO XmlOrderResponses (
    OrderResponseType
    ,OrderResponseNumber
    ,OrderResponseDate
    ,DocumentFunctionCode
    ,Remarks
    )
SELECT *
FROM OPENXML(@DocHandle, '/Document-OrderResponse/*', 11) WITH (
        OrderResponseType INT
        ,OrderResponseNumber NVARCHAR(40)
        ,OrderResponseDate DATETIME
        ,DocumentFunctionCode NVARCHAR(40)
        ,Remarks INT
        );

EXEC sys.sp_xml_removedocument @DocHandle;
