One element path that this module definition's criteria logic reads, relative to the resource retrieved. Repeats, once per distinct path. Finer-grained than dataRequirement, which bounds which resources are fetched: this bounds which of their elements have to be materialised for the logic to evaluate. A LOWER BOUND -- derived from retrieves and property accesses, without inference across included libraries -- so an absent path is not proof the logic never reads it.

Invariants

Every rule in force on a conforming instance. This profile rows are stated here; inherited rows come from the base resource and are listed so that a constraint named on an element is findable. Invariant keys elsewhere on this page link into this table.

Key	Source	Severity	On	Rule
criteria-elements-read-single-path	this profile	error	Extension	The value is ONE element path, not a delimited list: it must be non-empty and must not contain a comma. value.ofType(string).matches('^[^,]+$')
ele-1	inherited	error	Extension	All FHIR elements must have a @value or children hasValue() or (children().count() > id.count())
ext-1	inherited	error	Extension	Must have either extensions or value[x], not both extension.exists() != value.exists()
