> I'm testing out `iso9601-parse' with the example values from the vcard
> RFC, and am getting errors from the example date value "---12", from
> https://tools.ietf.org/html/rfc6350#section-4.3.1.
>
> My understanding is that "---12" as a date should parse to:

> (nil nil nil 12 nil nil nil -1 nil)
>
> Ie, "the twelfth" (though the twelfth of what, we don't know). "----12"
> also raises an error. The value "--0412" parses correctly to "April
> twelfth".

> Is this a bug that can be fixed, or a date value that isn't supported?
