I mean RFC4880 5.12. User Attribute Packet (Tag 17). 

I don't think signature notations are really the right meaning here. In
the case of a Bitcoin address I don't see any reason why the address
should be conceptually tied to a specific user-id. Secondly it's
perfectly reasonable to want to revoke a specific bitcoin address,
perhaps because it's not longer used or compromised, similar to how you
might want to revoke a user ID. Notations on signatures conflate a few
different meanings there.
