Why is the Register necessary?
Aggregators and other intermediaries typically lack direct knowledge needed to distinguish an authoritative source of alert messages
This lack becomes more critical as alerting makes more use of large public networks
The Register of Alerting Authorities is a reference to address that knowledge gap
Each Register entry asserts that a particular source of alert messages is regarded by a WMO Member as authoritative
