The lowest-order bit of the Flags field is 1 for an
announcement and 0 for a withdrawal. For a Prefix PDU
(IPv4 or IPv6), the flag indicates whether this PDU
announces a new right to announce the prefix or
withdraws a previously announced right; a withdraw
effectively deletes one previously announced Prefix PDU
with the exact same Prefix, Length, Max-Len, and
Autonomous System Number (ASN). Similarly, for a Router
Key PDU, the flag indicates whether this PDU announces a
new Router Key or deletes one previously announced
Router Key PDU with the exact same AS Number,
subjectKeyIdentifier, and subjectPublicKeyInfo.

The rationale for this approach is that the entire purpose of
