<t>Passive DNS Servers capture DNS answers from multiple collection points ("sensors") which are located on the Internet-facing side of DNS recursors ("post-recursor passive DNS"). In this process, they intentionally omit the source IP, source port, destination IP and destination port from the captured packets.

1. define an ENTITY at the top, and use "ampersand character"RFC2629; here (as shown)

2. simply use a PI "less than character"?rfc include="reference.RFC.2119.xml"?> here
