DURABLE: The status of this row entry. Rows are added to this table using 'row sets'. When a row is added, this object must be set to row-valid(1). To delete a row from this table, set this object for the row to row-invalid(2). Row sets for new rows with a row status set to row-invalid(2) return a BAD VALUE error. This object will always read as row-valid(1). If no more rows can be added to the end of the table, then a row set to create a new row will return BAD VALUE. When rows are deleted from this table, the indexes of the other rows do not change. In other words, this table can be 'sparse' or have 'holes'. Deleted entries can be re-created using a row set with a row status of row-valid(1).
