RLOC/ SET / USET in UCF file

Sorry that I can not input Chinese at lab ...
Our lab has a design which is written in Xilinx 8.1. The UCF file has a line like this:
SET "Bus2IP_Addr" RLOC_ORIGIN=X0Y0;
"Bus2IP_Addr" is a U_SET already defined in design file (.vhd).
It works OK with version 8.1.
However, in version 10.1, this does not work: SET is not a valid constraint command anymore.
I tried to use:
INST "Bus2IP_Addr" RLOC_ORIGIN=X0Y0;
But also failed. Because "Bus2IP_Addr" is not a real instance name but a set name.
Anybody has any idea how to deal with this problem?
I've googled a lot but can't find an answer. (Apparently, sb is using "set" in older version successfully.)
Thanks！
