Of course it will be good to have it. I do not negate this. But i suppose it is not required at start. >>With attributes, example: name="name", and not <Name>name</Name>. >>Nodes only for structures. I do not know if this will be flexible. Think about future when more detailed information will be presented. e.g. something like Postgress present. I do not suppose that this will be good to have such info in attributes. But maybe it will be ok? <Node-Type>Sort</Node-Type> <Parallel-Aware>false</Parallel-Aware> <Startup-Cost>611720.33</Startup-Cost> <Total-Cost>611741.43</Total-Cost> <Plan-Rows>8437</Plan-Rows> <Plan-Width>281</Plan-Width> <Sort-Key> <Item>w.insp_id</Item> <Item>w.konto_id</Item> <Item>w.wplata_data_wyciagu</Item> <Item>w.wplata_nr_wyciagu</Item> <Item>w.wplata_nr_pozycji</Item> </Sort-Key> Regards, Karol Bieniaszewski Firebird-Devel mailing list, web interface at https://lists.sourceforge.net/lists/listinfo/firebird-devel
