TRUNCATE TABLE problem...

I'm having a problem (well, two, one major, one minor) trying to TRUNCATE a table owned by another user.

(same problem in both 7.0.16 and 7.2.2)

User A owns the table (A.FOO), and user B needs to be able to TRUNCATE it.

Logged in as user B, TRUNCATE TABLE FOO results in table or view does not exist. (FOO is a public synonym to A.FOO, and A.FOO has been granted SELECT, INSERT, UPDATE, DELETE to B via a role which has been set.)

Logged in as user B, TRUNCATE TABLE A.FOO results in insufficient privileges.

First question: Why doesn't TRUNCATE follow the public synonym, even though it is valid and B can see A.FOO after the role has been set?

Oracle documentation says that to be able to TRUNCATE a table outside of one's own schema that the account must have DELETE ANY TABLE. We granted DELETE ANY TABLE to B and tried the same two TRUNCATE commands
(TRUNCATE TALBE FOO, TRUNCATE TABLE A.FOO) result
in the same two errors.

Second question: What do I have to grant to B (can it be to B, or to a role B has?) so it can truncate a table owned by A? (The public synonym thing is a problem I can live with, this isn't.)
