     * The ·lexical space· of dateTime consists of finite-length sequences of characters of the form:
     * '-'? yyyy '-' mm '-' dd 'T' hh ':' mm ':' ss ('.' s+)? (zzzzzz)?, where
     *
     * * '-'? yyyy is a four-or-more digit optionally negative-signed numeral that represents the year;
     *   if more than four digits, leading zeros are prohibited, and '0000' is prohibited (see the Note above (§3.2.7);
     *   also note that a plus sign is not permitted);
     * * the remaining '-'s are separators between parts of the date portion;
     * * the first mm is a two-digit numeral that represents the month;
     * * dd is a two-digit numeral that represents the day;
     * * 'T' is a separator indicating that time-of-day follows;
     * * hh is a two-digit numeral that represents the hour; '24' is permitted if the minutes and seconds represented
     *   are zero, and the dateTime value so represented is the first instant of the following day
     *   (the hour property of a dateTime object in the ·value space· cannot have a value greater than 23);
     * * ':' is a separator between parts of the time-of-day portion;
     * * the second mm is a two-digit numeral that represents the minute;
     * * ss is a two-integer-digit numeral that represents the whole seconds;
     * * '.' s+ (if present) represents the fractional seconds;
     * * zzzzzz (if present) represents the timezone (as described below).
