Murray pointed out that I STILL had it wrong.  Uploaded again with a much better version :)

   MAILBOXID-OPT = ":mailboxid" objectid

   FCC-OPTS =/ MAILBOXID-OPT

objectid is defined in RFC8474 as:

      objectid = 1*255(ALPHA / DIGIT / "_" / "-")
              ; characters in object identifiers are case
              ; significant

Of course now that I've posted this, I do wonder if I actually need to make it:

MAILBOXID-OPT = ":mailboxid" SPACE DQUOTE objectid DQUOTE

*sigh*.

I mean, RFC8580 already doesn't seem to be very specific about the whitespace between tokens - but I expect we probably do want the mailboxid to be a string rather than an objectid for parser simplicity.  I welcome input on that!  (I'm pretty sure the parser we have in Cyrus right now needs it to be a string for example)

Cheers,

Bron.
