I'm running on 8.3, but in that version at least, it looks like you have
a few options for the values and one of these should hopefully work in
8.2.

VALUES (1, ROW(23, 'ee', ROW('2005-01-01', '2005-12-31')));
VALUES (1, '(23,"ee","(2005-01-01,2005-12-31)")')
There are other slight variations on this second one, you can remove the
double quotes around ee and it looks like you can add double quotes around
the dates, etc.

It also looks like your attibute type above only had 2 scalars and the
complex type rather than three, so I've dropped the 'ttt' for the examples
above.
