Membership of the class TemporalUnit is open, to allow for other temporal units used in some technical applications (e.g. millions of years, Baha'i month).

Remove enumeration from definition, in order to allow other units to be used when required in other coordinate systems. NOTE: existing units are still present as members of the class, but the class membership is now open. In the original OWL-Time the following constraint appeared: owl:oneOf ( time:unitSecond time:unitMinute time:unitHour time:unitDay time:unitWeek time:unitMonth time:unitYear ) ;
