purpose:
  v: This extension is part of the cross-version definitions generated to enable use of the element `ImagingSelection.instance` as defined in FHIR R5 in FHIR R4. The source element is defined as: `ImagingSelection.instance` 0..* `BackboneElement` Across FHIR versions, the element set has been mapped as: * R5 `ImagingSelection.instance` 0..* `BackboneElement` Following are the generation technical comments: Element `ImagingSelection.instance` is not mapped to FHIR R4, since FHIR R5 `ImagingSelection` is not mapped. Element `ImagingSelection.instance` has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element).

  v: Element `ImagingSelection.instance.imageRegion3D` is part of an existing definition because parent element `ImagingSelection.instance` requires a cross-version extension. Element `ImagingSelection.instance.imageRegion3D` is not mapped to FHIR R4, since FHIR R5 `ImagingSelection` is not mapped. Element `ImagingSelection.instance.imageRegion3D` has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element).

  v: Element `ImagingSelection.instance.imageRegion2D.coordinate` is part of an existing definition because parent element `ImagingSelection.instance.imageRegion2D` requires a cross-version extension.

Element `ImagingSelection.instance.imageRegion2D.coordinate` has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element).

definition:
  v: The coordinates describing the image region. Encoded as a set of (column, row) pairs that denote positions in the selected image / frames specified with sub-pixel resolution. The origin at the TLHC of the TLHC pixel is 0.0\0.0, the BRHC of the TLHC pixel is 1.0\1.0, and the BRHC of the BRHC pixel is the number of columns\rows in the image / frames. The values must be within the range 0\0 to the number of columns\rows in the image / frames.
