We all understand that anything resembling a syntax error in the

Yes, as the text is clearer in the draft with the reference to Section 7.8.
Does that need to be more explicit?
No.
In Section 4.1.4:
"The SMTP client MUST, if possible, ensure that the domain
parameter to the EHLO command
is a valid principal host name (not a CNAME or MX name) for its host."
you use "valid principal host name". I suggest that it be changed to:
"The SMTP client MUST, if possible, ensure that the domain
parameter to the EHLO command
is a primary host name (a domain name that resolves to an A RR)
for its host."
That's the same as what is specified in Section 2.3.5 for the EHLO command.
