Date¶
Provides the structure of a Date element, which allows a choice between single, simple dates (of BaseDateType) or date ranges. If the Date element contains a range, Cycle may be used to indicate occurrence of this range within a series of ranges as an integer identifying the cycle, i.e. the 4th wave of a data collection cycle would have. BaseDateType allows for different date time combinations to provide a simple and convenient mechanism to specify different date and time values with a machine actionable format specified by regular expressions.
