CodeSystem/$lookup is able to return a code's properties and sub-properties.
The capability to include a concept's properties in the result of a ValueSet/$expand has been added to R5, but the changes to ValueSet.expansion.contains only support the ability to return properties and not sub-properties.
Proposal is to add ValueSet.expansion.contains.property.sub-property 0..* with sub-elements code and value[x]. This would also necessitate changing the cardinality of ValueSet.expansion.contains.property.code to 0..1
