HL7 Data types allow for time ranges to be specified by any two of low, high, center and width. There are six different combinations here. I have found only two of the six to be necessary: low and high, or width alone when a time range is known, but not it's anchors.
The rationale for constaining this is that it dramatically simplifies how the information is stored without any loss in what is conveyed.
