This is a value set defined by the FHIR project.
How an extension context is interpreted.
|Committee:||FHIR Infrastructure Work Group|
|OID:||2.16.840.1.113883.4.642.3.1012 (for OID based terminology systems)|
|Source Resource||XML / JSON|
This value set is used in the following places:
This value set contains 3 concepts
|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.|

Explanation of the columns that may appear on this page:
|Lvl||A few code lists that FHIR defines are hierarchical - each code is assigned a level. For value sets, levels are mostly used to organize codes for user convenience, but may follow code system hierarchy - 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|
|Definition||An explanation of the meaning of the concept|
|Comments||Additional notes about how to use the code|
