By the way, would it be possible to change the date format used in the SRFIs? I'd like to suggest the international standard date format (ISO 8601), i.e. YYYY-MM-DD. It's unambiguous and already in quite wide use around the net, especially in technical circles. It's also recommended by IETF as RFC 3339: <https://tools.ietf.org/html/rfc3339>.
