H.323V4 error (prior message mistitled)

(THIS IS A REPEAT MESSAGE, THE FIRST HAD THE WRONG SUBJECT)

In reading H.323V4 (from APC-1874), I noticed in the procedures of section
10.4.3 (tunneling of a signalling protocol in H.225.0 call signalling
messages) a reference to a tunnelledRequired flag, which doesn't exist.

Can the following change be made to H.323V4, or at least captured in the
Implementers Guide (assuming this error has not already been corrected)?

Section 10.4.3, second paragraph:

If an endpoint will only allow the call to proceed if tunneling is
supported, it shall set the tunnellingRequired flag in the Setup message;
the

tunnelledRequired  (DELETE)

tunnellingRequired (REPLACEMENT)

flag shall not be included in any other message than Setup. If an endpoint
receives a tunnelledSignallingMessage with the tunnellingRequired flag set
in the Setup message and is not able to tunnel the protocol, it shall
terminate the call by sending a Release Complete with a reason of
tunnelledSignallingRejected; a tunnellingRequired flag in any other message
than Setup shall be ignored.
