17   4) One required parameter, the hold-param, is added to the MAIL
 
18      command using either the keyword "HOLDFOR" or the keyword
 
23      Using ABNF [n2], the syntax of this parameter is as follows:
 
25         future-release-interval = future-release-integer
 
27         future-release-date-time = Internet-style-date-time-UTC
 
31The last quoted ABNF production should be:
 
33         future-release-date-time = date-time
 
34            ; <date-time> defined in Section 5.6 of RFC 3339
 
39The ABNF contains a dangling production. An early draft shows that the RFC 3339 production date-time is what's intended (as Ned Freed found out).
 
41The RFC also has no examples. I have a working server implementation of this, so without examples I guess talking to my server is second best. Send me mail in case of interest.
