how can a user who is in a role assign his role to another user?

I create a role(eg. HighOperators), and add user 'ABC01' into it. 'ABC01'
is not a member of the sysadmin fixed server role or the db_owner fixed data
base role or the db_securityadmin fixed database role, can he assign his ro
le to another user?
In SQL Server Books Online, it says " Role owners can execute sp_addrolememb
er to add a member to any SQL Server role they own". but I don't know how to
set or get the a role's Owner.The only way I know to set the role owner is when you create
the role, specify the owner of the role in the second
argument for sp_addrole.
In terms of retrieving the owner, I don't remember there
being a direct way. I think it may be that the altuid in
sysusers is the uid for the owner of the role.
