      Add another section to the SNOMED CT filters on the SNOMED CT on FHIR page to support a "descendant of" (<) filter for SNOMED CT (in addition to the existing 'is a' filter).

      See 2020-11-12 Vocab WG Main call minutes.

      Description

      The SNOMED CT Expression Syntax says:

      descendantOf = "<"
      descendantOrSelfOf = "<<"

      I think FHIR descendent-of is exactly matching <, while FHIR is-a is exactly matching <<. That must mean that the FHIR SNOMED CT page is missing support for descendent-of.

      I noticed in STU3, but that omission is still true in the current build.

      Request to add support for descendent-of in SNOMED CT related value sets. I can see how constraint could support the use case, but constraint is a whole lot more powerful and harder to implement.
