Task Priority Detail Extension

Canonical	../StructureDefinition/nexus-task-priority-detail
Status	draft · 1.26.0
Base	Extension (constraint)
Context	Task.priority (element)
Source	FSH · JSON

A priority refinement finer than R4's request-priority vocabulary allows, currently one concept: trivial, meaning below routine. Task.priority binds required to a value set whose floor is routine and is a bare code with no second coding slot, so a refinement cannot be carried in the element itself. When this extension is present Task.priority SHALL be routine, so a consumer that ignores the extension sorts the task as routine -- an understatement rather than a mis-sort.

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
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()
