0. Extension
Definition

Indicates the time with a precision of only Year. This extension is to be used in lieu of data elements of type instant present within a FHIR Resource


Optional Extension Element - found in all resources.

Control10..1*
This element is affected by the following invariants: ele-1
Is Modifierfalse
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())

2. Extension.url
Definition

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

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.
