[basex-talk] collection('i_do_not_exist')/users/user[@name=()] is () even if i_do_not_exist does not exit

Hi, Either I found an interesting new XQuery feature or a bug: collection('i_do_not_exist')/some/path[@attr=()] retruns the empty sequence whereas collection('i_do_not_exist')/some/path throws an error err:FODC0002 so does collection('i_do_not_exist')/some/path[@attr="i_am_an_attr"] Am I missing something?
