ValueSet: ExtensionContextType (How an extension context is interpreted.)

4.3.16.245.1 Content

This code system http://hl7.org/fhir/extension-context-type defines the following codes:

Code	Display	Definition
fhirpath	FHIRPath	The context is all elements that match the FHIRPath query found in the expression.
element	Element ID	The context is any element that has an ElementDefinition.id that matches that found in the expression. This includes ElementDefinition Ids that have slicing identifiers. The full path for the element is [url]#[elementid]. If there is no #, the Element id is one defined in the base specification.
extension	Extension URL	The context is a particular extension from a particular StructureDefinition, and the expression is just a uri that identifies the extension.

Level

A few code lists that FHIR defines are hierarchical - each code is assigned a level. See Code System for further information.

Source

The source of the definition of the code (when the value set draws in codes defined elsewhere)

Code

The code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')

Display

The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
