Definition

Used to express an uncertain date(+time) value by specifying an allowed or observed upper and lower bound.

Comment:

Allows a range to be used in place of a date(+time) value when an exact value is not known, but the outer limits of allowable or possible is known. This extension can be used to specify a range of allowed times in the future, or known boundary times in the past.
