Section 5.3 says:

The following is an example file which might be used to define the
ISI.EDU zone.and is loaded with an origin of ISI.EDU:

@   IN  SOA     VENERA      Action\.domains (
                                 20     ; SERIAL
                                 7200   ; REFRESH
                                 600    ; RETRY
                                 3600000; EXPIRE
                                 60)    ; MINIMUM

        NS      A.ISI.EDU.
        NS      VENERA
        NS      VAXA
        MX      10      VENERA
        MX      20      VAXA

A       A       26.3.0.103

VENERA  A       10.1.0.52
        A       128.9.0.32

VAXA    A       10.2.0.27
        A       128.9.0.33


[...]

Note the use of the \ character in the SOA RR to specify the responsible
person mailbox "Action.domains@E.ISI.EDU".

It should say:

The following is an example file which might be used to define the
ISI.EDU zone.and is loaded with an origin of ISI.EDU:

@   IN  SOA     VENERA      Action\.domains (
                                 20     ; SERIAL
                                 7200   ; REFRESH
                                 600    ; RETRY
                                 3600000; EXPIRE
                                 60)    ; MINIMUM

        NS      A.ISI.EDU.
        NS      VENERA
        NS      VAXA
        MX      10      VENERA
        MX      20      VAXA

A       A       26.3.0.103

VENERA  A       10.1.0.52
        A       128.9.0.32

VAXA    A       10.2.0.27
        A       128.9.0.33


[...]

Note the use of the \ character in the SOA RR to specify the responsible
person mailbox "Action.domains@ISI.EDU".

Notes:

The introductory sentence and the following zone definition both correctly refer to the zone ISI.EDU. But the closing sentence noting the usage of "\." in the mailbox name erroneously expands the example to "Action.domains@E.ISI.EDU" instead of "Action.domains@ISI.EDU".
