Hi Anders,
In my opinion, a linkage scheme based on hashing the object to generate
its ID is better, because it imposes fewer requirements on issuers and
makes the scheme more robust. You can't accidently reuse your own or
somebody
elses ID, unless the hash has collided. It also serves as an additional
check
on the integrity of the linkage (incase you have accidently trusted a "bad"
issuer
generating IDs that are being used by another issuer). The latter may be
important if
you have many trust relationships.

Regards,
Nigel.
