R5: ValueSet.expansion.next (new:uri)


Optional Extension Element - found in all resources.

ShortR5: Opaque urls for paging through expansion results (new)Optional Extensions Element
Comments

Element ValueSet.expansion.next has a context of ValueSet.expansion based on following the parent source element upwards and mapping to ValueSet. Element ValueSet.expansion.next has no mapping targets in FHIR R4B. Typically, this is because the element has been added (is a new element). Clients SHOULD use the next link, if present, to page through expansion results in preference to using the offset and count parameters. Due to the optional nature of the next link, its absence does not necessarily indicate that it is the last page of results. Instead, as the offset and count parameters SHALL be populated when paging, clients can reliably use the count/offset parameters to determine whether the whole expansion is returned.

4. Extension.extension
Definition

May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

ShortAdditional content defined by implementations
Comments

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
