OK. At the moment the draft says:
3.5.7. Provisioning Domain Announcement
This message is sent by the MIF API to the subscriber to indicate
that a new Provisioning Domain has successfully been configured on an
interface. The announcement includes the interface identifier and
the provisioning domain identifier.
So let's add
According to [RFC4007], a scope zone is identified by a Zone Identifier.
In practice, a scope zone often corresponds to a single interface, so
interfaces are also identified by Zone Identifiers. For consistency,
provisioning domains too are identified by Zone Identifiers. In the
simplest case, a single Zone Identifier will name an interface, a scope
zone, and a provisioning domian. In more complex cases, an interface,
the scope zone it reaches, and the corresponding provisioning domain
will have different Zone Identifiers.
