Your problem does not need access types, and will be clearer and simpler without
them.

You could have maps:

(client ID)       -> (client info)
(subscription ID) -> (subscription info)

Client info may contain subscription IDs, and subscription info may contain
client IDs. If you have one and not another, you use the ID to obtain the info.
