How an extension context is interpreted.

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

fhirpath FHIRPathThe context is all elements that match the FHIRPath query found in the expression.btn btn
element Element IDThe 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.btn btn
extension Extension URLThe context is a particular extension from a particular StructureDefinition, and the expression is just a uri that identifies the extension.btn btn

Explanation of the columns that may appear on this page:

LevelA few code lists that FHIR defines are hierarchical - each code is assigned a level. See Code System for further information.
SourceThe source of the definition of the code (when the value set draws in codes defined elsewhere)
CodeThe code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
DisplayThe 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
