addr:AddressAnomalyStatus_type

A status flag, or an explanatory note, for an address
that is not correct according to the address schema in
which it is located, but is nonetheless a valid address.
This field may be used to identify the type of anomaly
(e.g. wrong parity, out of sequence, out of range, etc.)
rather than simply whether or not it is anomalous. Local
jurisdictions may create specific categories for
anomalies.
