 Although Aries Framework JavaScript tries to follow the standards as described in the Aries RFCs as much as possible, some features in AFJ slightly diverge from the written spec. Below is an overview of the features that diverge from the spec, their impact and the reasons for diverging.

+| Revocation Notification v1 uses a different `thread_id` format ( `indy::<revocation_registry_id>::<credential_revocation_id>`) than specified in the Aries RFC | Any agents adhering to the [revocation notification v1 RFC](https://github.com/hyperledger/aries-rfcs/tree/main/features/0183-revocation-notification) will not be interoperable with Aries Framework Javascript. However, revocation notification is considered an optional portion of revocation, therefore this will not break core revocation behavior. Ideally agents should use and implement revocation notification v2. | Actual implementations (ACA-Py) of revocation notification v1 so far have implemented this different format, so this format change was made to remain interoperable.    |
