Time range defined by start and end date/time
A time period defined by a start and end date and optionally time.
A Period specifies a range of time; the context of use will specify whether the entire range applies (e.g. "the patient was an inpatient of the hospital for this time range") or one value from the range applies (e.g. "give to the patient between these two times"). Period is not used for a duration (a measure of elapsed time). See [Duration](http://hl7.org/fhir/R5/datatypes.html#Duration).
All FHIR elements must have a @value or children
hasValue() or (children().count() > id.count())
If present, start SHALL have a lower or equal value than end
start.hasValue().not() or end.hasValue().not() or (start.lowBoundary() <= end.highBoundary())
n/a,IVL<TS>[lowClosed="true" and highClosed="true"] or URG<TS>[lowClosed="true" and highClosed="true"]
Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
Extensions are always sliced by (at least) url
Must have either extensions or value[x], not both
The start of the period. The boundary is inclusive.
If the low element is missing, the meaning is that the low boundary is not known.
End time with inclusive boundary, if not ongoing
The end of the period. If the end of the period is missing, it means no end was known or planned at the time the instance was created. The start may be in the past, and the end date in the future, which means that period is expected/planned to end at that time.
The end value includes any matching date/time. i.e. 2012-02-03T10:00:00 is in a period that has an end value of 2012-02-03.
If the end of the period is missing, it means that the period is ongoing
