Error in exporting DR$ tables

Question

Hi,
I have user(Say User1) with Roles CONNECT,RESOURCE,CTXAPP roles granted to it.
The entire schema except tables LIKE DR$ATTRIBUTE_VALUES_INDEX$I and DR$ATTRIBUTE_VALUES_INDEX$K and ATTRIBUTES view are not exported appropriately.
C:\>exp user1/user1@instance_name file=E:\code\Backup\temp\user1.dmp
log=E:\code\Backup\temp\user1.log rows=yes constraints=yes indexes=yes
grants=yes consistent=y;
On exporting the same i was encountered with

According to Metalink Note:139388.1:
This is intended behavior.
Secondary objects are not exported because the CREATE INDEX at import time
will recreate them.
The column 'SECONDARY' of DBA_TABLES indicates if the table is a secondary object
created by the ODCIIndexCreate method of the Oracle Data Cartridge (Y or N).
