time	Time Form: hh:mm:ss Example: 12:54:30

timePeriod	Form: PnYnMnDTnHnMnS Example: P65Y (65 years old) or Form: PnW Example: P12W (12 weeks after birth)

The format of the date, time, dateTime, and timePeriod should be specification of ISO 8601 [7], especially the Complete representation format. In addition, the format of the date, time, and dateTime should be the Extended format. The format of the timePeriod should be the Basic format. The range that can be omitted varies depending on the individual element. Refer to the element explanation for the format of individual elements and attributes.

In the future, if the specification of XML Schema is recommended by W3C, the XML Schema-Datatypes will be specified for the MML data type.
