Extension: CQFMIsTestCase - Detailed Descriptions

Active as of 2025-08-26

Definitions for the cqfm-isTestCase extension.

0. Extension
Definition

Indicates whether this instance represents the definition of a test case.


Optional Extension Element - found in all resources.

ShortTest Case?Optional Extensions Element
Control0..1*
This element is affected by the following invariants: ele-1
Is Modifiertruefalse because This extension is a modifier because it changes whether the MeasureReport is an actual measure report, or if it is a test case describing expected results
Invariantsele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
ext-1: Must have either extensions or value[x], not both (extension.exists() != value.exists())
ext-1: Must have either extensions or value[x], not both (extension.exists() != value.exists())
2. Extension.url
Definition

Source of the definition for the extension code - a logical name or a URL.

Shortidentifies the meaning of the extension
Comments

The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension.

4. Extension.extension
Definition

May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

Comments

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
