Resource Profile: Expanded ValueSet

Defines an executable value set as one that SHALL have an expansion included, as well as a usage warning indicating the expansion is a point-in-time snapshot and must be maintained over time for production usage. The value set expansion specifies the timestamp when the expansion was produced, SHOULD contain the parameters used for the expansion, and SHALL contain the codes that are obtained by evaluating the value set definition. If this is ONLY an executable value set, a computable definition of the value set must be obtained to compute the updated expansion.

Usage:

• This Resource Profile is not used by any profiles in this Implementation Guide

mustSupport When this profile has defined an element as mustSupport, the sender must provide the element value when available, and the receiver must accept the element value, persist the value and when appropriate, provide function as defined in the profile. When mustSupport is defined at a complex element level, all sub-elements inherit mustSupport.

mustSupport When this profile has defined an element as mustSupport, the sender must provide the element value when available, and the receiver must accept the element value, persist the value and when appropriate, provide function as defined in the profile. When mustSupport is defined at a complex element level, all sub-elements inherit mustSupport.
