            Value of the attribute associated with an item. Similar to columns on a spreadsheet, attributes represent
            categories of data that can be assigned to items. Allowed characters are all UTF-8 characters valid in
            XML documents. Control characters and any sequences that are not valid in XML are not allowed. These strings
            can be up to 1024 bytes long.
