This selection of choice types is a superset of the majority of choice types that are used as possible representations for timing-valued elements in FHIR, allowing this function to be used across any resource. The input can be provided as a dateTime, Period, Timing, instant, string, Age, or Range. The intent of this function is to provide a clear and concise mechanism to treat single elements that have multiple possible representations as intervals so that logic doesn't have to account for the variability. More complex calculations (such as medication request period or dispense period calculation) need specific guidance and consideration. That guidance may make use of this function, but the focus of this function is on single element calculations where the semantics are unambiguous. If the input is a dateTime, the result a DateTime Interval beginning and ending on that dateTime. If the input is a Period, the result is a DateTime Interval. If the input is a Timing, an error is raised indicating a single interval cannot be computed from a Timing. If the input is an instant, the result is a DateTime Interval beginning and ending on that instant. If the input is a string, an error is raised indicating a single interval cannot be computed from a string. If the input is an Age, the result is a DateTime Interval beginning when the patient was the given Age, and ending immediately prior to when the patient was the given Age plus one year. If the input is a Range, the result is a DateTime Interval beginning when the patient was the Age given by the low end of the Range, and ending immediately prior to when the patient was the Age given by the high end of the Range plus one year.
