Extension: Rendering Critical Extension

Official URL: http://hl7.org/fhir/uv/sdc/StructureDefinition/sdc-rendering-criticalExtension Version: 4.0.0
Standards status: Trial-use Maturity Level: 4 Computable Name: RenderingCriticalExtension
Other Identifiers: OID:2.16.840.1.113883.4.642.40.17.42.65

Indicates an extension that must be supported by the system presenting the instance for data capture or end-user consumption. If a system does not recognize the extension or cannot implement the functionality defined by the extension, it should display an error message or warning and refrain from presenting the instance to the user or using it when capturing data.

Allows systems to identify extensions that are critical for rendering or interacting with the resource in data capture or consumption scenarios.

Context of Use

    This extension may be used on the following element(s)

If this element appears at the root of a resource, then the expectation applies to all uses of the extension/element throughout the resource. If it appears on another element, the expectation for support of the extension/element only applies to the element on which the rendering-criticalExtension extension appears, and any descendants of that element.

If this extension is present, the instance SHALL populate the Resource.implicitRules element with a hyperlink pointing to this extension definition, with an expectation that systems will adhere to the expectations of this extension when presenting the resource.
