Setting New Sub Partition Template Has No Effect

Not sure if its an issue or just an Oracle "feature" of some sort. So I create a table with a specified partition/ sub partition template as follows:

CODEcreate table sr_part_test
(
part_key NUMBER,
subpart_key VARCHAR(10)
)
tablespace NORKOM_DATA
partition by range ( part_key )
subpartition by list ( subpart_key )
[code].......

Then when I split the MAX VALUE partition, all is hunky dorey and as expected:

CODEalter table sr_part_test split partition sr_part_max at (4) into
(
partition sr_part_4,
partition sr_part_max
);
select * from user_tab_subpartitions where table_name = 'SR_PART_TEST' and partition_name = 'SR_PART_4';
[code]......

But - what if I want to have new generated names and possibly even new subpartition keys? Won't work:

CODEalter table sr_part_test
set subpartition template
(
subpartition sp_1_NEWNAME values ('foo'),
subpartition sp_2_NEWNAME values ('bar'),
subpartition sp_3_NEWNAME values ('baz')
);
[code]........

Notice that the sub partition names are still using the old names (which I do NOT want), and still using the old keys! C .
