Hi Ken,

So in -07, I now see:

3.1.1.  Imap4flags Extension

    Usage: :fcc <mailbox: string> [:flags <list-of-flags: string-list>]

3.1.2.  Mailbox Extension

    Usage: :fcc <mailbox: string> [:create]

3.1.3.  Special-Use Extension

   Usage: :fcc <mailbox: string> [:specialuse <special-use-flag: string>]

Is your intention that :fcc always goes first? If not, you might want to 
clarify that.

3.2.  Collected Grammar

    For convenience, the "FCC" syntax element is defined here using ABNF
    [RFC5234] so that it can be augmented by other extensions.

    FCC         = ":fcc" string *FCC-OPTS

I am somewhat uncomfortable with the above, as it omits all whitespace 
delimiters between tokens. If you are going to keep this, you should add 
a comment explaining that this is done once lexical analyzer extracted 
different non-space elements.

Best Regards,
