      Add codes to the code system and value set for:

       'child'

      Corresponds to "DirectRelationsOnly with HeadCode = FALSE" is VSD.

      'descendant-leaf'

      Corresponds to "TransitiveClosureLeaves with HeadCode = FALSE" in VSD.

      The analogous codes in VSD for "DirectRelationsOnly with HeadCode = TRUE" and "TransitiveClosureLeaves with HeadCode = TRUE" can be supported in FHIR by adding an additional 'include' in the ValueSet.compose for the head code itself.

      Request: Add values to the FilterOperator value set

      Context: create a Profile on ValueSet that aligns with Value Set Definition.

      FilterOperator has a required binding to to compose.include.filter.op https://www.hl7.org/fhir/valueset-filter-operator.html

      VSD models 2 elements to define what corresponds to compose.include.filter.op. One of which is a boolean (ContentSystemElement.CodeBasedContent.IncludeRelatedCodes.IncludeHeadCode) and the other is a code with required values to define traversal (ContentSystemElement.CodeBasedContent.IncludeRelatedCodes.RelationshipTraversal) (TransitiveClosureLeaves, DirectRelationsOnly, TransitiveClosure)

      The combinations available with the two VSD elements are not all covered in the FilterOperator value set. For details - see https://confluence.hl7.org/display/VOC/Resource+element+list row 57

      The following VSD allowed combinations are missing from the value set and need to be added (codes TBD)

      DirectRelationsOnly with HeadCode = FALSE

      DirectRelationsOnly with HeadCode = TRUE

      TransitiveClosureLeaves with HeadCode = FALSE

      TransitiveClosureLeaves with HeadCode = TRUE

      (note: VSD TransitiveClosure with HeadCode = TRUE maps to FilterOperator "is-a"

      VSD TransitiveClosure with HeadCode = FALSE maps to FilterOperator "descendant-of"
