('-120.4') or scientific notation ('-1.204e2').

=item 'boolean'

A boolean true/false value. The number '0' represents false, and '1'
represents true.

=item 'dateTime.iso8601'

A string representation for a date/time combination in the gregorian
calendar. The format is very specific, as follows:

    YYYY-MM-DDTHH:MM:SS[.ffff]TZ

Here, YYYY is the four-digit year (actually, the year can be greater
than four digits, or negative). MM is the 2-digit month of the year,
from '01' to '12'. DD is the day of the month, ranging from '01' to
'31'. The 'T' is a literal character 'T' (assumably to specify
'time'), and 'HH' is the hour, ranging from '00' to '23'. 'MM' is the
minute part, from '00' to '59', and SS is the seconds, '00' to '59'.
