  "description": "Sometimes it is not possible to use the ValueSet from the functional description on the corresponding FHIR element. This is a common occurence when the FHIR element has datatype _code_ and has a _required_ binding with an incompatible FHIR core ValueSet. It can also happen when the FHIR element has a _string_ or other non-coded datatype.\\r\\n\\r\\nIn this case, the FHIR element may be augmented with this extension to communicate the code from the functional description. This information should always be _added_ to the normal use of the FHIR element to allow for maximum interoperability.",
