Extension: BodyDistanceFromExtension - Detailed Descriptions

Definitions for the BodyDistanceFromExtension Extension

1. Extension
Definition

This complex extension adds fields that form a distance measurement from a specified body landmark. The body landmark is defined by a codeable concept The distance is defined by a quantity of metric distance units (cm, mm, etc).

Control0..* This element is affected by the following invariants: ele-1
InvariantsDefined on this element
ele-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())
2. Extension.id
Definition

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

SlicingThis element introduces a set of slices on Extension.extension. The slices are ordered and Open at End, and can be differentiated using the following discriminators:
  • value @ url
4. Extension.extension:landMark

Definition

Body landmark which defines the origin of the measurement.

Currently the value set this is bound to does not contain the required breast landmarks like nipple.
