ch-emed-event-timing	warning	Dosage.timing.repeat.when	For the representation of the time of administration according to the 1-1-1-1 scheme, the values MORN-NOON-EVE-NIGHT are highly recommended. : $this='MORN' or $this='NOON' or $this='EVE' or $this='NIGHT'
ele-1	error	**ALL** elements	All FHIR elements must have a @value or children : hasValue() or (children().count() > id.count())
ext-1	error	**ALL** extensions	Must have either extensions or value[x], not both : extension.exists() != value.exists()
only-standard-event-timings	error	Dosage.timing.repeat.when	The timing event shall only be 'MORN', 'NOON', 'EVE' or 'NIGHT'. : $this = 'MORN' or $this = 'NOON' or $this = 'EVE' or $this = 'NIGHT'
tim-1	error	Dosage.timing.repeat	if there's a duration, there needs to be duration units : duration.empty() or durationUnit.exists()
tim-2	error	Dosage.timing.repeat	if there's a period, there needs to be period units : period.empty() or periodUnit.exists()
tim-4	error	Dosage.timing.repeat	duration SHALL be a non-negative value : duration.exists() implies duration >= 0
tim-5	error	Dosage.timing.repeat	period SHALL be a non-negative value : period.exists() implies period >= 0
tim-6	error	Dosage.timing.repeat	If there's a periodMax, there must be a period : periodMax.empty() or period.exists()
tim-7	error	Dosage.timing.repeat	If there's a durationMax, there must be a duration : durationMax.empty() or duration.exists()
tim-8	error	Dosage.timing.repeat	If there's a countMax, there must be a count : countMax.empty() or count.exists()
tim-9	error	Dosage.timing.repeat	If there's an offset, there must be a when (and not C, CM, CD, CV) : offset.empty() or (when.exists() and ((when in ('C' | 'CM' | 'CD' | 'CV')).not()))
tim-10	error	Dosage.timing.repeat	If there's a timeOfDay, there cannot be a when, or vice versa : timeOfDay.empty() or when.empty()
